ubifs: auth: Add CONFIG_KEYS dependency

The new authentication support causes a build failure
when CONFIG_KEYS is disabled, so add a dependency.

fs/ubifs/auth.c: In function 'ubifs_init_authentication':
fs/ubifs/auth.c:249:16: error: implicit declaration of function 'request_key'; did you mean 'request_irq'? [-Werror=implicit-function-declaration]
  keyring_key = request_key(&key_type_logon, c->auth_key_name, NULL);
