Subject: [PATCH]  Merge #14947: scripts: Remove Python 2 import workarounds

4de11a3682 Remove Python 2 import workarounds (practicalswift)

Pull request description:

  Remove Python 2 import workarounds.

  As noted by @jnewbery in https://github.com/bitcoin/bitcoin/pull/14903#discussion_r241396925:

  > This exception handling is a vestige from when github-merge.py supported Python 2 and Python 3. We only support Python 3 now so we should be able to remove it entirely and just import from urllib.request.
