fetchgit: make sparseCheckout a list of strings
The `sparseCheckout` argument allows the user to specify directories or patterns of files, which Git uses to filter files it should check-out. Git expects a multi-line string on stdin ("newline-delimited list", see `git-sparse-checkout(1)`), but within nixpkgs it is more consistent to use a list of strings instead. The list elements are joined to a multi-line string only before passing it to the builder script. A deprecation warning is emitted if a (multi-line) string is passed to `sparseCheckout`, but for the time being it is still accepted.
