temp/mesa-git: re-add dev() and define provides for -dev package (!924)
This fixes 1943ead2689510192b403486380c667e5aec644f, which accidentally
removed the dev() function that generates the mesa-git-dev package..
causing mesa-dev to be pulled in in cases where mesa-dev is required
(and failing because mesa-dev is older)
