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 forces all maps to the maps section so we remain compatible with
libbpf. This requires #181 to avoid breaking userspace.

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 allows for C code to be compiled and used in tests!
It does require libbpf on the host machine though...
Also moved removal of the `user` and `ebpf` dirs created by rust-script
into `lib.sh` and parameterized bits of the XDP smoke test for ease of
copying

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
