Add config options which are needed for LKDTM sub-tests.
STACKLEAK_ERASING test needs GCC_PLUGIN_STACKLEAK config.
READ_AFTER_FREE and READ_BUDDY_AFTER_FREE tests need
INIT_ON_FREE_DEFAULT_ON config.
CFI_FORWARD_PROTO always fails as there is no active CFI system of some
kind. Turn it off for now by default until proper support.
