lfs: add git to the User-Agent header for blob transfers
As we were trying to transition off of the non production lfs-test-server for
further experimenting, one of the problems we ran into was interoperability. A
coworker setup gitbucket[1] to act as the blob server, tested with git, and
passed it off to me. But push failed with a message saying "abort: LFS server
returns invalid JSON:", and then proceeded to dump a huge HTML page to the
screen. It turns out that it is assuming that git is the only thing that wants
to do a blob transfer, and everything else is a web browser wanting HTML.
It's only a single data point, but I suspect other things may be doing this too.
RFC7231 gives an example [2] of listing multiple products in decreasing order of
significance. Since the standard provides for this, and since it works with the
one problematic server I found, I'm just enabling this by default for a better
UX.
There's nothing significant about the version of git chosen, other than it is
the current version.
