aya: Find programs using the symbol table This makes a few changes to the way that Aya reads the ELF object files. 1. To find programs in a section, we use the symbols table. This allows for cases where multiple programs could appear in the same section. 2. When parsing our ELF file we build symbols_by_section_index as an optimization as we use it for legacy maps, BTF maps and now programs. As a result of theses changes the "NAME" used in `bpf.prog_mut("NAME")` is now ALWAYS the same as the function name in the eBPF code, making the user experience more consistent.

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.
