This commit adds PinnedProgram which allows the creation of a Program
from a path on bpffs. This is useful to be able to call `attach` or
other APIs for programs that are already loaded to the kernel.
Unfortunately figuring out the concrete type of program is hard given
the information in the kernel so this may not work for all program
types.

This commit allows for BTF maps in the .maps ELF section to be parsed.
It reads the necessary information from the BTF section of the ELF file.
While the btf_ids of Keys and Values types are stored, they are not (yet)
used.
When creating a BTF map, we pass the btf_key_type_id and
btf_value_type_id.

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.
