kunit: allow kunit tests to be loaded as a module
As tests are added to kunit, it will become less feasible to execute all built tests together. By supporting modular tests we provide a simple way to do selective execution on a running system; specifying CONFIG_KUNIT=y CONFIG_KUNIT_EXAMPLE_TEST=m ...means we can simply "insmod example-test.ko" to run the tests. To achieve this we need to do the following: o export the required symbols in kunit o string-stream tests utilize non-exported symbols so for now we skip building them when CONFIG_KUNIT_TEST=m. o drivers/base/power/qos-test.c contains a few unexported interface references, namely freq_qos_read_value() and freq_constraints_init(). Both of these could be potentially defined as static inline functions in include/linux/pm_qos.h, but for now we simply avoid supporting module build for that test suite. o support a new way of declaring test suites. Because a module cannot do multiple late_initcall()s, we provide a kunit_test_suites() macro to declare multiple suites within the same module at once. o some test module names would have been too general ("test-test" and "example-test" for kunit tests, "inode-test" for ext4 tests); rename these as appropriate ("kunit-test", "kunit-example-test" and "ext4-inode-test" respectively). Also define kunit_test_suite() via kunit_test_suites() as callers in other trees may need the old definition.
