Report keyguard changes even with display changes

Display changes shouldn't be played by remote animations unless
shell is allowed to play rotation animations.

Keyguard updates must make it to the keyguard handler so that keyguard
gets the right information about lock/unlock state.

If these rules conflict, the second one wins because the consequences
are worse.
