kunit: Fix kunit.py --raw_output option

[ Upstream commit 3023d8f ]

Due to the raw_output() function on kunit_parser.py actually being a
generator, it only runs if something reads the lines it returns. Since
we no-longer do that (parsing doesn't actually happen if raw_output is
enabled), it was not printing anything.
