support/download: relocate the git clone comment
Following commit 95a572282e87 (pkg-infra: move the git download helper to a script, 2014-07-02), move the comment describing the shallow clone trickery as well. Merge this comment with the existing helper comment that was added in 7e40a1103a91 (support/download: convert git to use the wrapper, 2014-08-03). Rename $($(PKG)_DL_VERSION) to ${cset} to match the helper code context. Cc: "Yann E.
