libbpf: Search /lib64 and /lib in resolve_full_path()

attach_probe/uprobe-lib and uprobe_autoattach selftests fail with "failed
to resolve full path for libc.so.6" on older non-usrmerged distros, where
libc.so.6 lives under a top-level /lib64 or /lib rather than /usr/lib64 or
/usr/lib. Add /lib64:/lib to the search paths, alongside the existing
/usr/lib64:/usr/lib and Debian multiarch entries.
