Use <cmath> instead of <math.h> to get std::isnan

During the exp-run in bug 208158, it was found that graphics/opencollada gi=
ves
errors with libc++ 3.8.0 [1]:

/wrkdirs/usr/ports/graphics/opencollada/work/OpenCOLLADA-a59a438/GeneratedS=
axParser/src/GeneratedSaxParserUtils.cpp:1559:16:
error: no member named 'isnan' in namespace 'std'; did you mean simply 'isn=
an'?
        return std::isnan(value);
               ^~~~~~~~~~
               isnan

This is because opencollada's GeneratedSaxParserUtils.cpp includes <math.h>,
not <cmath>.  The latter defines std::isnan(), so use it instead.
