Revert "makepkg: Use a recursive git clone."

This reverts commit 8b03b1a877.

It is much better to download the submodules using separate source entries
and adjust the submodule configs to point at these versions in the
prepare() function.

See https://mailman.archlinux.org/pipermail/pacman-dev/2013-March/016771.html
for an example.
