[PATCH 1/3] ui/sdl2: Grab Alt+Tab also in fullscreen mode

[Bernhard Beschow]

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+F4 in fullscreen mode, always causing tasks to be switched in
the VM.
