SCI32: Fix integer overflow calculating audio duration
Due to the need to calculate the audio duration with millisecond
precision from the file size, it is possible to overflow a 32-bit
integer in games with long background audio loops, like RAMA,
during the calculation of the duration.
It is also not necessary to give some framerate here, so eliminate
the unnecessary explicit Timestamp construction with the second
argument.
