fix BadMatch error when embedding on some windows

When embedded, st fails with BadMatch error if the embedder's window has
non-default colormap/depth/visual.  This commit fixes that by creating
st's window inside root and then reparent it into embedder.

The reference window for dc.gc is also changed to match root's visuals.

A similar commit had been made for dmenu[1].
See this issue[2] on github for context.
