[bug#31582] [PATCH 8/8] gnu: Add git-annex.

[Christopher Lemmer Webber <cwebber@dustycloud.org>]

I tested this morning.  It seems to work well.

My one comment before I push this is a minor one... should this go in
backup.scm or should it be in version-control.scm?  Not everyone is
using it in ways I would consider to be "backups" any more than other
VCS things are... I'm not.
