Subject: SCI: Fix control/Fx keys not working anymore

Was effectively caused by commit adding the keyboard driver bug
for SCI0/SCI01, although the bug is actually real and happens.

It seems Sierra did not check the key-modifier in kMenuSelect.
We do and that's why the code didn't recognize all sorts of
menu keys anymore.
We now isolate the lower byte before comparing.

I also noticed, that Sierra passed keyboard modifiers in mouse
events. This was probably done, so that owners of a 1-button
mouse were able to right-click. We do this now too.

Also added information about mouse modifiers in kGetEvent.

Moved the mouse modifier code into getScummVMEvent().

This should fix bug #7009.
