Add fix for the empty ${D}${localedir} bug

This gets rid of the following Error:

    ERROR: QA Issue: eglibc-locale: Files/directories were installed but not shipped
       /usr/lib/locale

A patch is already available: http://lists.openembedded.org/pipermail/openembedded-core/2013-November/085826.html
We need this bbappend until this fix is integrated into dora.

This fixes #6 in project-magpie/meta-stlinux
