Please help backport 3c107f36db06 selftests/net: mv bpf/nat6to4.c to net folder to v6.1-rt

Hi Clark,

Is it OK to backport 3c107f36db06 ("selftests/net: mv bpf/nat6to4.c to net folder")
to v6.1-rt? The selftest always failed[1] with error like "./nat6to4.o: Permission denied".
The issue has been fixed and backported to all stable kernels except v6.1-rt[2].
