[Buildroot] [PATCH v2] pkg-download: take some more care of <PKG_>VERSION with git

[Patrick Boettcher]

This replaces the one-liner patch I made last week after a comment by
Thomas De Schampheleire. (it is now a 5-liner)

I added comment to explain why using HEAD is better in the current
situation. I did not change the hg-part as it is different to git -
after a quick read it won't work at all when VERSION is not set in a
packge.

Please apply if appropriate and helpful (it is for me).
