Subject: [PATCH] backends/x11: Present surface even with empty damage

All the other backends present their surface regardless.
If the surface isn't presented, the scheduled frame is never
finished, and rendering gets stuck indefinitely.

This is also consistent with x11 standalone backend
which forgoes this check.
