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:

rustfmt: group_imports = "StdExternalCrate" 
High time we stop debating this; let the robots do the work.
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.

integration-test: compile C probes using build.rs 
- Add libbpf as a submodule. This prevents having to plumb its location
  around (which can't be passed to Cargo build scripts) and also
  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.

Shenghui Ye 81bc307dce aya-obj: migrate bindgen destination 
Aya::obj depends on bindgen generated files, and we start
by migrating bindgen generated files.

This commit adds the new aya-obj crate to the workplace
and migrates generated files into the crate. We use core
instead of std in an effort to make the final crate no_std.

Bindgen was run against libbpf v1.0.1.
