eglibc-package.inc: Remove duplicate locale install

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.
