Subject: [PATCH] selftests/bpf: Fix bpf selftest build warning

On linux-next, build for bpf selftest displays a warning:

Warning: Kernel ABI header at 'tools/include/uapi/linux/if_xdp.h'
differs from latest version at 'include/uapi/linux/if_xdp.h'.

Commit 8066e388be48 ("net: add UAPI to the header guard in various network headers")
changed the header guard from _LINUX_IF_XDP_H to _UAPI_LINUX_IF_XDP_H
in include/uapi/linux/if_xdp.h.

To resolve the warning, update tools/include/uapi/linux/if_xdp.h
to align with the changes in include/uapi/linux/if_xdp.h
