Precedence: bulk

The new implementation of kunit_test_suite() for modules no longer
conflicts with module_init, so can now be used by the thunderbolt tests.

Also update the Kconfig entry to enable the test when KUNIT_ALL_TESTS is
enabled.

This means that kunit_tool can now successfully run and parse the test
results with, for example:
	./tools/testing/kunit/kunit.py run --arch=x86_64 \
	--kconfig_add CONFIG_PCI=y --kconfig_add CONFIG_USB4=y \
	'thunderbolt'

Changes since v1:
https://lore.kernel.org/linux-kselftest/20220618090310.1174932-4-davidgow@google.com/
- Actually include the Kconfig changes, which were mistakenly added to
  the next patch in the series in v1.
- Add Acked-by tag from Mika Westerberg
