most of bpf tests require root access as well.

'make kselftest' doesn't work for me at all, since I suspect it
assumes in-source build. I always use KBUILD_OUTPUT,
since I build multiple archs with different configs out of the same
source tree, so there is a bigger problem here.

$ make kselftest
make[1]: Entering directory `/data/users/ast/net-next/bld_x64'
make: Entering an unknown directory
make: *** tools/testing/selftests: No such file or directory. Stop.
make: Leaving an unknown directory
make[1]: *** [kselftest] Error 2
make[1]: Leaving directory `/data/users/ast/net-next/bld_x64'
make: *** [sub-make] Error 2
