[CUDA] Mark CUDA as a no-errno platform.
Summary:
CUDA doesn't support errno at all, so this is the right thing -- or at
least, in the right direction.
But also, this unbreaks the CUDA test-suite math tests [0] after D39481.
__cuda_cmath.h forwards nexttoward() to __builtin_nexttoward, which,
after that patch, was lowering to a libcall that doesn't exist in NVPTX.
