kunit: add support for kunit_suites that reference init code

Add support for a new kind of kunit_suite registration macro called
kunit_test_init_section_suite(); this new registration macro allows the
registration of kunit_suites that reference functions marked __init and
data marked __initdata.

/**
* kunit_test_init_section_suites() - used to register one or more &struct
* kunit_suite containing init functions or
* init data.
*
* @__suites: a statically allocated list of &struct kunit_suite.
*
* This functions identically as &kunit_test_suites() except that it suppresses
* modpost warnings for referencing functions marked __init or data marked
* __initdata; this is OK because currently KUnit only runs tests upon boot
* during the init phase or upon loading a module during the init phase.
*
* NOTE TO KUNIT DEVS: If we ever allow KUnit tests to be run after boot, these
* tests must be excluded.
*
* The only thing this macro does that's different from kunit_test_suites is
* that it suffixes the array and suite declarations it makes with _probe;
* modpost suppresses warnings about referencing init data for symbols named in
* this manner.
