tsdemux: Fix scaling macros

Browse source 
While the calculation done in these macros will work with 64bit
integers, they will fail if working with 32bit integers.

Force the scaling up to solve that.

This amazingly didn't introduce major issues up to now, but resulted
in bogus values in debug logs.
