selftests/bpf: Tests for BPF_SK_LOOKUP attach point
Add tests to test_progs that exercise:
- attaching/detaching/querying programs to BPF_SK_LOOKUP hook,
- redirecting socket lookup to a socket selected by BPF program,
- failing a socket lookup on BPF program's request,
- error scenarios for selecting a socket from BPF program,
- accessing BPF program context,
- attaching and running multiple BPF programs.
