Summary:
This is called when creating a slave from a master pty and returns a file descriptor.
Usage example:
```
async fn handle_ioctl<G: Guest<Self>>(
&self,
guest: &mut G,
syscall: Ioctl,
) -> Result<i64, Errno> {
use reverie::syscalls::ioctl;
match syscall.request() {
ioctl::Request::TIOCGPTPEER(flags) => {
let fd = guest.inject(syscall).await?;
// Do something with the flags and fd ...
Ok(fd)
}
_ => Ok(guest.inject(syscall).await?)
}
}
```

Summary: Adds support for the `clone3` syscall, which is now used by `pthread_create`. This also introduces `CloneFamily`, which abstracts `fork`, `vfork`, `clone`, and `clone3`.
