ANDROID: net: bpf: Allow TC programs to call BPF_FUNC_skb_change_head

This enables ebpf tethering offload from a cellular interface with
no L2 mac header to a wifi/ethernet/usb interface with one.

Will pursue upstreaming this along with further mtu related fixups.

Test: builds, real testing with identical patch on a 4.14 flame device
