Teach --exec to git-archive --remote

Some people needed --exec to specify the location of the upload-pack
executable, because their default SSH log-in does not include the
directory they have their own private copy of git on the $PATH.
These people need to be able to say --exec to git-archive --remote
for the same reason.
