Support running with polyinstantiated /tmp
Quoting the commit:
xwayland: Make sure /tmp/.X11-unix/ exists
When we're running under a polyinstantiated SELinux environment, we'll likely start with an isolated and empty /tmp, meannig no /tmp/.X11-unix directory to add things to. To make it possible to still function in this kind of setup, make sure said directory exists.
Marked WIP since it includes !1625 (merged).
