Fix configuration changes in status bars.

- Make sure SystemBars calls onConfigurationChanged on the
  status bar
- Remove redundant ACTION_CONFIGURATION_CHANGED receiver in
  BaseStatusBar & move this code into onConfigurationChanged
- Force locale refresh even if a configuration change
  touches only the layout direction
