Billy McFall 62efed1853 chore(xtask): Add s390x and powerpc64 to codegen 
This commit adds the s390x and powerpc architectures
to codegen. This will enable an upcoming PR to add
support for aya to support theses architectures
in both aya and aya-ebpf.

tyrone-wu b23973dd9c xtask: corrected bpf to ebpf for path to aya-ebpf-bindings in codegen 
Currently, when running `cargo +nightly xtask codegen` locally and in
the codegen GHA workflow, an error occurs with only "Error: bindgen
failed" displayed.

This was due to a path using "bpf/..." instead of "ebpf/...". It is now
corrected to "ebpf", and bindgen fails should now display a more direct
message on why it failed.

Fixes: #914

integration-ebpf: invalidate on bpf-linker 
Extract the symlink-to-bpf-linker logic from integration-test to xtask
and use it in a new build script in integration-ebpf, causing ebpf
probes to be rebuilt when bpf-linker changes. Previously bpf-linker
changes would rebuild integration-test, but not integration-ebpf,
resulting in stale tests.

Note that this still doesn't address the possibility that a new
bpf-linker is added to the PATH ahead of the cached one. Solving this in
the general case would require rebuild-if-changed-env=PATH *and*
rebuild-if-changed={every-directory-in-PATH} which would likely mean far
too much cache invalidation.

Andrew Werner d5259ce789 xtask: move libbpf submodule 1 year ago
Andrew Werner 15b3c459ae xtask: ensure libbpf submodule is initialized 
Libbpf is used by xtasks, in the command, ensure that the submodules
are initialized. This eases the user-experience so that users don't
need to think about the submodule, while retaining all the benefits
of using a submodule vs forcing the user to manually check out libbpf
and stick it in some pre-defined place.

We use the symbol pointing to libbpf in xtask in the build script
to avoid repeating this constant.

Also, we install git in the vm so that we can init the submodule
when we build in the vm.

xtask: remove assumptions from docs command 
This slightly changes the site layout: crate documentation is now flat
rather than being nested under "user" and  "bpf".

- Run `cargo clean --doc` before generating docs to ensure hermiticity.
- Generate header.html into a temporary directory.
- Remove "site" on each run to ensure hermiticity.
- Invoke cargo only once.
- Avoid editing sources.

integration-test: build "fake" by default 
Use the environment variable AYA_BUILD_INTEGRATION_BPF to indicate to
the build script that it should *actually* build bpf, otherwise emitting
empty files.

This allows metadata builds to skip costly build steps without
sacrificing ergonomics; all compile-time tools such as cargo clippy work
out of the box.

Cargo even gives each of these builds (depending on the value of the
environment variable) its own cache key, so they do not invalidate each
other when the user alternates between metadata and real builds.

This allows the lint action to move out of the VM.

integration-test: compile C probes using build.rs 
- Add libbpf as a submodule. This prevents having to plumb its location

  controls the version against which codegen has run.
- Move bpf written in C to the integration-test crate and define
  constants for each probe.
- Remove magic; each C source file must be directly enumerated in the
  build script and in lib.rs.
