wrap: Ignore directories that have a .wrap with the same name
wrap: Ignore directories that have a .wrap with the same name

If we update e.g. glib.wrap from wrap-git with directory=glib to
wrap-file with directory=glib-2.70 we could still have the glib
directory that is not referenced by any .wrap file any more. We should
still ignore that directory otherwise it overrides the glib.wrap we
parsed.
