This moves the docs for downloading kernels into the integration-test
README since it allows us to be more verbose.
Instructions have been added for the use of Fedora kernels.
The instructions for Debian kernels were amended to not download all the
kernels, and to encourage targetted download of the one you care about.

Implements running integration tests on multiple VMs with arbitrary
kernel images using `cargo xtask integration-test vm ...`.
This changes our coverage from 6.2 to 6.1 and 6.4.
Move the use of clang and llvm-objcopy from run-time to build-time. This
allows the integration tests to run on VMs with simpler userlands.
Create a new CI job to build the integration tests separately from
running them. Ship them from that job to the runner job using github
actions artifacts.
- 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.
This doesn't add any value; use `cargo build --tests` with
`--message-format=json` instead; parse the output using `cargo_metadata`
to discover the location of the test binary.
Move test/integration-test/src/tests -> test/integration-test/tests to
conform to
https://doc.rust-lang.org/book/ch11-03-test-organization.html#integration-tests.
This commit replaces the existing RTF test runner with a simple rust
binary package called - integration-test.
integration-test depends on integration-ebpf, which contains test eBPF
code written in Rust and C. `cargo xtask build-integration-test-ebpf`
can be used to build this code and supress rust-analyzer warnings. It
does require `bpf-linker`, but that is highly likely to be available to
developers of Aya. It also requires a checkout of `libbpf` to extract
headers like bpf-helpers.h.
Since everything is compiled into a single binary, it can be run
be run locally using `cargo xtask integration-test` or remotely using
`./run.sh` which re-uses the bash script from the old test framework
to spawn a VM in which to run the tests.

This commit uses the symbol table to discover all maps inside an ELF
section. Instead of doing what libbpf does - divide the section data
in to equal sized chunks - we read in to section data using the
symbol address and offset, thus allowing us to support definitions
of varying lengths.

This uses a mix of rust-script, bash, qemu and a test runner called RTF
to add a regression test suite... and wires it into GitHub Actions
