Merge branch 'bpf-selftests'

Daniel Borkmann says:

====================
Move to BPF selftests

This set improves the test_verifier and test_maps suite and moves
it over to a new BPF selftest directory, so we can keep improving
it under kernel selftest umbrella. This also integrates a test
script for checking test_bpf.ko under various JIT options.
