ANDROID: kunit: Provision kunit as a vendor module

Browse Source 
'kunit_test' member variable in task_struct is defined
under CONFIG_KUNIT. Besides there are supportive functions
in slub and kasan which gets conditionally compiled out.

Allow kunit to be build as vendor module by removing
compile time dependencies.
