libbpf: remove unused libbpf_strerror_r and STRERR_BUFSIZE

Browse Source 
libbpf_strerror_r() is not exposed as public API and neither is it used
inside libbpf itself. Remove it altogether.

Same for STRERR_BUFSIZE, it's just an orphaned leftover constant which
we missed to clean up some time earlier.
