kunit: unify module and builtin suite definitions
Currently, KUnit runs built-in tests and tests loaded from modules differently. For built-in tests, the kunit_test_suite{,s}() macro adds a list of suites in the .kunit_test_suites linker section. However, for kernel modules, a module_init() function is used to run the test suites. This causes problems if tests are included in a module which already defines module_init/exit_module functions, as they'll conflict with the kunit-provided ones. This change removes the kunit-defined module inits, and instead parses the kunit tests from their own section in the module. After module init, we call __kunit_test_suites_init() on the contents of that section, which prepares and runs the suite. This essentially unifies the module- and non-module kunit init formats.
