qtmux: Be more clever with the default video track timescale

Use the number of milliframes per second for integral and drop-frame
framerates, as suggested by the QT file format specification and other
places. We already did that for integral framerates before, but not for
drop-frame framerates. This now keeps precision better.

For all other framerates, check if it's close to a well-known framerate
and use that instead.
