[libc-commits] [libc] [libc] Fix missing errno include in fuzzer (PR #144132)

[Michael Jones via libc-commits]

https://github.com/michaelrj-google created https://github.com/llvm/llvm-project/pull/144132

The printf parser uses errno for setting up the %m conversion. It was
presumably getting this include indirectly until a recent change. This
patch adds a direct dependency to fix it.
