Remove Makefile dependencies for test targets

These are probably here because the executables aren't always built for
other platforms (e.g. Windows); however we can safely assume they'll
always be there. None of the other test targets have such dependencies
and if we don't remove them, make tries to rebuild the executables and
fails during run-ptest.
