ima: define '.ima' as a builtin 'trusted' keyring
Require all keys added to the IMA keyring be signed by an existing trusted key on the system trusted keyring.

Kasatkin) - only make the IMA keyring a trusted keyring (reported-by D. Kastatkin) - define stub integrity_init_keyring() definition based on CONFIG_INTEGRITY_SIGNATURE, not CONFIG_INTEGRITY_ASYMMETRIC_KEYS.
