Subject: [PATCH 09/11] selftests: lib.mk: copy test scripts and test files for make O=dir run

For make O=dir run_tests to work, test scripts, test files, and other
dependencies need to be copied over to the object directory. Running
tests from the object directory is necessary to avoid making the source
tree dirty.
