state: handle ACTION_LOCK_NO_{UN,}LOCK for mods

xkblib spec says:
    XkbSA_LockNoLock    If set, and the action type is XkbSA_LockMods,
                        the server only unlocks the action modifiers.
    XkbSA_LockNoUnlock  If set, and the action is XkbSA_LockMods,
                        the server only locks the action modifiers.
