sys/linux: support multi-progs for BPF_PROG_ATTACH
Commit [1] upstream, and subsequent patches, extended the
BPF_PROG_ATTACH command to support a new multi-prog object in the BPF
subsystem. In particular, programs can now be attached relative to
another object (relative_obj), a BPF program or link, referenced via
either an fd or a BPF ID (id_or_fd). In addition, a new concept of BPF
revision number was introduced and a revision number can be passed, to
be checked at attach time. Finally, the attachment target can now also
be an ifindex.
