midori: upgrade to 0.4.4

* custom waf to fix dirty vala version was dropped
* I've fixed our vala to stop reporting dirty even for valid released tarballs
  so you can still get dirty version but it's not so common to keep this ugly binary here.
* disable PARALLEL_MAKE to improve our chances agains build hangs
  (btw fedora is doing the same
