Fix type for abs() calls in multimedia/vdr

During the exp-run in bug 208158, it was found that multimedia/vdr gives errors with libc++ 3.8.0 [1]:

dvbdevice.c:769:18: error: call to 'abs' is ambiguous
     frequency = abs(frequency); // Allow for C-band, where the frequency is less than the LOF
                 ^~~

This is because 'frequency' is unsigned, and it is therefore ambiguous to which type it should be casted before calling abs().  Two similar ambiguities exist in remux.c.  Fix these by explicity casting the arguments to int.
