SCUMM: Glitches with the bus in ZAK

[GermanTribun]

System: Windows 10 x64
ScummVM: Newest 2.7.9git
Game versions: C64 and FM-Towns

There are a few small problems with the the bus in SanFancisco. Nothing game-breaking, but it's there.

-On the C64, the sound of the bus starting it's engine is not heard before the the scene changes to the airport. (the sound is heard when playing on an emulator)

-On the FM-Towns the bus driver doesn't again look forward after his comment after Zak has paid and before the scene change (something he does in all other versions) and still looks to Zak up until the scene changes. There also is no engine sound, but it's unknown to me if such a sound is even present in this version.

I can confirm that there is no engine sound in the original, and the bus driver facing Zak's direction is totally normal too. So this part is really not a bug. The C64 part appears to definitely be a bug though...
