wayland: don't try to use a non-existing viewporter interface

Browse source 
When instantiating the viewport for a pointer surface, we didn't first
check if the compositor implements the viewporter interface.

This triggered a crash when a) foot was compiled with fractional
scaling, and b) the compositor did not implement the viewporter
interface.

Closes #1444

* Regression: line- and box drawing characters not covering the full
height of the line, when a custom `line-height` is being used
([#1430][1430]).
* Crash when compositor does not implement the _viewporter_ interface
