glibc-package.inc: correct intention for deleting /usr/lib as needed

In case the baselib is lib64 we would want to delete /usr/lib
after removing the /usr/lib/locale dir and the implementation
wanted to do that earlier as well but the fault was checking
an already removed dir (/usr/lib/locale) before trying to
remove /usr/lib as that check would always fail.
Now we simply try to delete /usr/lib after deleting
/usr/lib/locale to make sure it deletes cleanly and is empty
at the time of deletion.
