[PATCH 02/12] selftests: Fix output directory with O=

[Geert Uytterhoeven]

When building kselftest in a separate output directory, the individual
test directories end up in the root of the output directory, instead of
under tools/testing/selftests/.

Fix this by passing the expected path to the make subprocess.
