[PATCH 5/9] compositor: fix shell panel and background setup

[Pekka Paalanen]

The problem was diagnosed by Benjamin Franzke. This patch is a quick fix
he showed, extended to fix also the background.

If wlsc_surface has no output assigned, the 'frame' event is never sent.
This causes dri2_swap_buffers() in Mesa (wayland platform) to spin on
wl_display_iterate() only reading mesages. Therefore messages are never
actually sent again.

This patch fixes panel button hilighting (panel redraws altogether), and
also screen unlocking.
