x11: Use Atoms when constructing a new MetaX11SelectionOutputStream

Browse Source 
This was pointlessly being converted between atom and string and back,
which with the switch from gdk_x11_get_xatom_name() to XGetAtomName()
also introduced a leak for every XGetAtomName() call.

Fixes: e66f4396e ("x11: Avoid GDK API in X11 selections")
