bpf: Support all gso types in bpf_skb_change_proto()
Since we no longer modify gso_size, it is now theoretically
safe to not set SKB_GSO_DODGY and reset gso_segs to zero.
This also means the skb_is_gso_tcp() check should no longer
be necessary.
Unfortunately we cannot remove the skb_{decrease,increase}_gso_size()
helpers, as they are still used elsewhere:
bpf_skb_net_grow() without BPF_F_ADJ_ROOM_FIXED_GSO
bpf_skb_net_shrink() without BPF_F_ADJ_ROOM_FIXED_GSO
net/core/lwt_bpf.c's handle_gso_type()
