[Libguestfs] Whenjobs automating libguestfs development version test & build

Just a note that 'whenjobs'[1] is now automating libguestfs test and
build, along the development branch.

Simply tagging a new release in git will trigger a cycle of packaging,
test, build, updating the website, and performing a new build in
Fedora Rawhide.

At the moment I'm only doing the tests on Fedora, but I will extend it
later so it tests both individual commits and released tarballs on
Debian, Ubuntu & RHEL.

I also want to extend it to build/test/release stable branches.

The current whenjobs script is attached.
