cuda_nvcc: also patch math_functions.hpp for glibc 2.42

Browse Source 
The existing glibc 2.42 compatibility patch fixes function signatures
in math_functions.h but misses math_functions.hpp, which has the same
rsqrt/sinpi/cospi functions wrapped in __func__() macros. Without
throw() annotations on these, C++ compilation fails when glibc 2.42
declares the same functions with throw().
