InputManager: Add system setting to define keyboard locales 

KEYLAYOUT_OVERRIDES expects a string of "devicename,layoutfile" to set
keyboard layout and character map to files in /system/usr/keylayout and
/system/user/keychars.

This overrides the default behaviour of opening files that match the
device's input name if there's no configuration file.
