bpf: add skb->tstamp r/w access from tc clsact and cg skb progs
This could be used to rate limit egress traffic in concert with a qdisc
which supports Earliest Departure Time, such as FQ.
Write access from cg skb progs only with CAP_SYS_ADMIN, since the value
will be used by downstream qdiscs. It might make sense to relax this.
Changes v1 -> v2:
- allow access from cg skb, write only with CAP_SYS_ADMIN
