By default, SDL grabs Alt+Tab only in non-fullscreen mode. This causes Alt+Tab
to switch tasks on the host rather than in the VM in fullscreen mode while it
switches tasks in non-fullscreen mode in the VM. Fix this confusing behavior
by grabbing Alt+Tab in fullscreen mode, always causing tasks to be switched in
the VM.
