xwayland: (Re)set seat when xwayland is ready

Browse source 
For some reason wlroots will reset the seat assigned to xwayland
to NULL whenever Xwayland terminates. This patch restores the seat
whenever Xwayland is ready again.

Fixes #166
Fixes #444

Thanks @droc12345 for figuring out the actual issue.
