devel: script for checking a commit (series)

'check-notmuch-commit' is an updated version of a script I have been
using (although not always as consistently as I should) before sending
patches to the list.

Although it requires a bit more tooling, encouraging people to use
check-notmuch-commit might reduce the number of round trips to the
list for style nitpicks.
