Augustin Cavalier 218604196a libroot: Fix ICU locale implementation of wcsxfrm.
* The "size" parameter is the size of "out" not "in", and the
   return size_t parameter is supposed to always have the total amount
   of wchar_ts needed, not how many are actually used.
 * In the case where "outSize == 0", we set "requiredSize" and then
   return.

Fixes crashes seen in glib2 Unicode collation routines, which
are used in GTK file dialogs.

Thanks to PulkoMandy for glancing at this.
