[PATCH] git-clone: stop dumb protocol from copying refs outside heads/ and tags/.

Most notably, the original code first copied refs/remotes/ that
remote side had to local, and overwrote them by mapping refs/heads/
from the remote when a dumb protocol transport was used.

This makes the clone behaviour by dumb protocol in line with the
git native and rsync transports.

 * This is another one of those patches I've been doing recently
   after making --use-separate-remote the default.  Judging from
   my experience in the past few days, it is quite surprising
   that none of these were found and reported earlier, given
   that many people made loud noises to make separate-remote the
   default layout.  Maybe they do not eat their own dog food?  I
   honestly do not know...
