of: Allow overlay kunit tests to run CONFIG_OF_OVERLAY=n

Browse Source 
Some configurations want to enable CONFIG_KUNIT without enabling
CONFIG_OF_OVERLAY. The kunit overlay code already skips if
CONFIG_OF_OVERLAY isn't enabled, so this select here isn't really doing
anything besides making it easier to run the tests without them
skipping. Remove the select and move the config setting to the
drivers/of/.kunitconfig file so that the overlay tests can be run with
or without CONFIG_OF_OVERLAY set to test either behavior.
