KEYS: remove CONFIG_KEYS_COMPAT

KEYS_COMPAT now always takes the value of COMPAT && KEYS.  But the
security/keys/ directory is only compiled if KEYS is enabled, so in
practice KEYS_COMPAT is the same as COMPAT.  Therefore, remove the
unnecessary KEYS_COMPAT and just use COMPAT directly.

(Also remove an outdated comment from compat.c.)
