Avoid freeze on Atari TT / MegaSTe boot with continues messages of:
unexpected interrupt from 112
Which was due to VBL interrupt being enabled in SCU sys mask, but
there being no handler for that any more.
Fixes: 1fa0b29f3a43f9dd
Reported-By: Nicolas Pomarède and Christian Zietz
(Bug and fix verified first on real Atari TT by Christian Zietz,
this patch later on in Hatari emulator.)
