backends: Fallback to builtin panel for devices where all heuristics fail

This is 1) relatively likely as not all touchscreens are nice enough to
report a device size that will help us here and 2) Better than nothing if
everything fails anyway, as it will break on multi-monitor and non-default
monitor rotations.
