fix not to display error log about the absense of compose file

All locale information except 'en_US.UTF-8' had been removed as a part of
the uninstallation of unnecessary resources except the essential elements for
basic key-mapping funtionality. As a result, if a locale is set to other than
'en_US.UTF-8', an error  message is being displayed that says a compose file
cannot be found.

Actually, there is no problem with the behavior but it is often perceived by
the developer(s) and tester(s) as an error. Thus, this fixes the search error
for the compose file for another locale other than 'en_US.UTF-8' to not be
displayed anymore.
