[build] Add a script for installing db4
Instead of maintaining not-easily-tested instructions for building BerkeleyDB in doc/build-unix.md, package the installation as a script in contrib/. This allows shared usage from a number of contexts, e.g. Docker. Thanks to @jonasschnelli, @laanwj for feedback.
