tools headers: Fixup tools/include/uapi/linux/bpf.h copy of kernel ABI header

In 2be7e212d5 ("bpf: add bpf_skb_adjust_room helper") BPF_ADJ_ROOM_NET was
added to include/uapi/linux/bpf.h but BPF_ADJ_ROOM_NET_OPS was added to
tools/include/uapi/linux/bpf.h, making these files differ, fix it by using the
same name in both, BPF_ADJ_ROOM_NET, the one in the kernel headers copy.
