Add support for FD_IDX and make libbpf prefer that approach to loading programs
to make testing and bisection easy.
The next patch will fine tune libbpf behavior to use FEAT_FD_IDX only when
generating loader program.

Patch #15 pretty much undoes this patch, but leaves unused FEAT_FD_IDX
and probe_kern_fd_idx() lying around. Is there a problem to just put
bpf_object__relocate_data()'s changes into patch #15?
