[PATCH v6 06/12] integrity: Introduce asymmetric_sig_has_known_key()

IMA will only look for a modsig if the xattr sig references a key which is not in the expected kernel keyring. To that end, introduce asymmetric_sig_has_known_key(). The logic of extracting the key used in the xattr sig is factored out from asymmetric_verify() so that it can be used by the new fun
