Dave Tucker bf7fdff1ce 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.

integration-test: compile C probes using build.rs
- 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.
