selftests/bpf: add test program for loading BPF ELF files
V2: Moved program into selftests/bpf from tools/libbpf
This program can be used on its own for testing/debugging if a
BPF ELF-object file can be loaded with libbpf (from tools/lib/bpf).
If something is wrong with the ELF object, the program have
a --debug mode that will display the ELF sections and especially
the skipped sections. This allows for quickly identifying the
problematic ELF section number, which can be corrolated with the
readelf tool.
The program signal error via return codes, and also have
a --quiet mode, which is practical for use in scripts like
selftests/bpf.
