create-finkdb.pl still uses cvs

[TheSin-]

create-finkdb.pl still uses cvs, it needs to be converted to use git.

Also it's pretty inefficient. I think it should checkout fink-distributions into the workdir via clone, and check if .git/config exists and just do a pull -q on it.

Then for each release it should just make a symlink back to the work/fink-distrutions path to avoid having a bunch of checkouts that are the same. This kinda worked for cvs since it didn't clone all dists, but in git this will be a waste and much slower.
