Subject: [PATCH] Implement AsRawFd for &Pty

Some APIs, like `nonblock::NonBlockingReader::from_fd`
take a value that implements AsRawFd.

Pty implements AsRawFd, but if we pass it by value, it will
get moved, as it doesn't implement Clone or Copy.

With this change, &Pty can now be passed without moving the
Pty.
