use locale-archive to prevent basic command performance regression

Browse Source 
all the basic command like chgrp/chmod/chown/mkdir/touch
will first search /use/lib/locale/locale-archive. if failed,
then search the exact locale like /usr/lib/locale/zh_CN.
right now we don't have locale-archive and this will cause the
basic command's performance regression, so add it.
