[libc-commits] [libc] [libc] Fix utimes build when full_build=OFF (PR #149668)

[Mikhail R. Gadelha via libc-commits]

https://github.com/mikhailramalho created https://github.com/llvm/llvm-project/pull/149668

Same as PR #149665: we might pull a header from the host where tv_nsec is not a long, so compilation would fail with an implicit conversion error.
