libgimp: set_i18n() method of GimpPlugIn expects UTF-8 catalog directory. 

Nothing was really clearly specified until now, which was kinda equivalent to
the string being in the OS encoding as used by GLib. Since this string will
usually be statically hardcoded in code (and not extracted from system), it's
just much easier to request UTF-8 for this specific case.
