[mythtv] Should llabs() be used instead of abs() for long long int?

[Matthew Parris]

I ran into a compile error on my QNAP NAS with Marvell 6282 1.6GHz (ARM)
and kernel 2.6.33.2:

transcode.cpp:541: error: call of overloaded 'abs(long long int)' is
ambiguous

When I edited the code and changed from abs to llabs, the compile was
successful.  Is this a particular for my system or would other systems
benefit from this change?  Patch text below:
