cudaPackages.cuda_crt: patch math_functions.h signatures, python3Packages.deep-ep: cleanup, fix build on CUDA>=13.0

Things done

This PR addresses the mismatch in function declarations between glibc and cuda CRT.

The issue was already addressed for CUDA<13.0 (#484031), but is still relevant with CUDA>=13.0.
Indeed, the patch already targeted all CUDA versions, before realizing that it failed to apply on CUDA>=13.0.
Thus, it was removed in #488738, assuming it was not needed however.
Yet, while some functions are now fine (sinpi, cospi), rsqrtand rsqrtf still need to be patched.
They are not declared in cuda_nvcc anymore, but in cuda_crt.

nice!

The only failure (python3Packages.cuda-bindings.gpuCheck) is not a regression. I plan to address it in #512828.
-> merged!
