Described in POSIX: https://pubs.opengroup.org/onlinepubs/9799919799/functions/access.html
The `faccessat` function is a syscall wrapper that checks if a file is available.
This will be very similar to the `access` syscall wrapper, implemented here: https://github.com/llvm/llvm-project/blob/2e83f10121b79dc39559ede2efcf34864088beec/libc/src/unistd/linux/access.cpp#L24
Here's a checklist for what you'll need to do for this:
- [ ] Add the implementation of `faccessat` in [`/src/unistd`](https://github.com/llvm/llvm-project/tree/main/libc/src/unistd)
- [ ] Add tests for `faccessat` in [`/test/src/unistd`](https://github.com/llvm/llvm-project/tree/main/libc/test/src/unistd)
- [ ] Add `faccessat` to [`entrypoints.txt`](https://github.com/llvm/llvm-project/blob/main/libc/config/linux/x86_64/entrypoints.txt) for at least x86_64 and whatever you're building on
- [ ] Add `faccessat` to [`include/unistd.yaml`](https://github.com/llvm/llvm-project/blob/main/libc/include/unistd.yaml)
