Merge #11702: [build] Add a script for installing db4

6e4cdd6 [docs] Add reference to install_db4.sh in OS X build instructions (James O'Beirne)
af9103e [build] Add a script for installing db4 (James O'Beirne)

Pull request description:

  Instead of maintaining rote instructions for building BerkeleyDB in `doc/build-{unix,openbsd}.md`, reference a script that does the same thing and can be called from unanticipated contexts, e.g. Docker builds.

  The script was written with portability in mind, though I haven't tested it on openbsd.

  I wasn't sure if we wanted to create a separate directory for this sort of thing (e.g. `contrib/install`) so I just stuck it in `contrib/`; happy to move it around if anyone has another preference.
