The kernel test robot reports undefined reference to
public_key_verify_signature when CONFIG_ASYMMETRIC_PUBLIC_KEY_SUBTYPE is
not defined. Create a static version in this case and return -EINVAL.

Perhaps this patch wouldn't be needed if
+config INTEGRITY_MACHINE_KEYRING
+ bool "Provide a keyring to which CA Machine Owner Keys may be
added"
+ depends on SECONDARY_TRUSTED_KEYRING
+ depends on INTEGRITY_ASYMMETRIC_KEYS
depends on ASYMMETRIC_PUBLIC_KEY_SUBTYPE=y
+ depends on SYSTEM_BLACKLIST_KEYRING
+ depends on LOAD_UEFI_KEYS
