git-download: Use a single download script for all derivations.
That way, we have only one /gnu/store/…-git-download instead of one /gnu/store/…-PACKAGE-checkout-builder for each package. This is a followup to ced200328ca6337ac446e4557c645629e7d7a997. * guix/git-download.scm (git-fetch)[build]: Get the URL, commit, and recursive parameter using 'getenv'. Pass #:script-name and #:env-vars arguments to 'gexp->derivation'.
