configure: require bash >= 4.1 at compile time 

We've unofficially agreed to raise our minimum supported bash version to
4.1, and since added features that require it. Additionally, an earlier
commit adds a syntax check to the builds of scripts/ and contrib/ which
could conceivably fail with an earlier shell. Therefore, make this a
hard requirement of the build process.
