[libc-commits] [libc] [libc] Fix setitimer build when full_build=OFF (PR #149665)

[Mikhail R. Gadelha via libc-commits]

https://github.com/mikhailramalho created https://github.com/llvm/llvm-project/pull/149665

When we pull the headers from the system, we might get a suseconds_t that's a long long, so add a cast to prevent a implicit conversion error.

that's a long long, so add a cast to prevent a implicit conversion
error.
