Switch to dosemu VT if config.forcevtswitch is set.
The idea of this action is that in case of config.console_video
dosemu need to work at active VT (at least at start) for accessing
video memory. So to be able to run dosemu for instance
through cron we need config option like forcevtswitch.
The action seems sensible only if config.console_video.
