kunit: fix Kconfig for build-in tests USB4 and Nitro Enclaves

Both the USB4 and Nitro Enclaves KUNIT tests are now able to be compiled
if KUNIT is compiled as a module. This leads to issues if KUNIT is being
packaged separately from the core kernel and when KUNIT is run baremetal
without the required driver compiled into the kernel.

Fixes: fe5be808 ("nitro_enclaves: test: Use kunit_test_suite() macro")
