Documentation: Adjust guidelines regarding math.h header

Browse source 
While libcamera prefers usage of the C standard library headers (xxx.h)
over the C++ version (cxxx), we make an exception for cmath as the
overloaded versions of the math functions are convenient. Document this,
and adjust checkstyle.py accordingly.
