Summary: SKY: Possible fix for crash when changing scaler

Initial Comment:
ScummVM sometimes crashes if you change scaler during
the CD intro. I think that is because update_screen()
is being called from two different threads, without any
safety net against races. This patch attempts to fix
that, but I'm a bit uncertain about exactly which
functions need to be guarded so it may be slightly
wrong and/or incomplete.
