Both eglibc-locale and eglibc were installing locale files into the sysroot.
Whilst this is in general harmless, its a waste of diskspace/time so this
moves the responsibility to the eglibc-locale package.
No PR bump this this is really a cleanup and doesn't affect build output,
the sstate size reduction will happen next time it is rebuilt.
