[PATCH weston 2/2] weston-test: don't map surfaces that have no content

[Emilio Pozuelo Monfort]

If a surface has no content (e.g. no buffer), then it shouldn't
be mapped, so that its subsurfaces don't get mapped either.

This works fine in the desktop-shell, but is currently broken
on the weston-test module.
