console: Fix widget size with scaling=never and host fractional scaling

Browse Source 
We can not reliably use VM desktop resolution for host widget
sizes when the host is using desktop scaling, so don't even try.

This fixes the black bars around the VM console when scaling=never
and autoresize is disabled
