net: bpf: Allow TC programs to call BPF_FUNC_skb_change_head
This allows TC eBPF programs to modify and forward (redirect) packets
from interfaces without ethernet headers (for example cellular)
to interfaces with (for example ethernet/wifi).
The lack of this appears to simply be an oversight.
Tested:
in active use in Android R on 4.14+ devices for ipv6
cellular to wifi tethering offload.
