Title: [RFC] Avoid printing an error response when detecting xclip.

While we're at, using the slightly more portable hash technique to
detect the executable. Also, there's no need to use `io.popen()` if we
aren't going to record the path. Instead, let's use the simpler
`os.execute()` to detect the presence of xclip.
