Revert "Keyguard: Use translucent UI"

This isn't the correct implementation. We should be enabling transparency in the status bar and navigation bar through: <bool name="config_enableLockScreenTranslucentDecor">true</bool> in frameworks-res.

This MIGHT also be the cause for transparency to not be working properly sometimes upon wake, but not sure about that yet.

This reverts commit 81ead53ff75deb3ee7e3ff186c8eff835bf0d2ea.
