Andrew Werner 97eb8afeac integration-test: use nightly toolchain with ebpf
The ebpf probes require a nightly compiler. Before this change, if you
ran `cargo xtask integration-test` with a stable compiler toolchain as
default, or you ran `cargo +stable xtask integration-test`, you would
have seen an error like the one below. This is now fixed by running the
cargo build command in the integration-ebpf directory and making sure
to clear the RUSTUP_TOOLCHAIN env var.

```

Remove detritus
- rustfmt settings are hierarchical.
- integration-ebpf is always compiled at a distance with flags provided.
- .cargo/config.toml is not respected except at the root of the
  workspace[0].

Dave Tucker 79101e748a test: Replace RTF with Rust
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.
