Remove trailing slash from MR_REPO.

This avoids double slashes in paths used in:

(a) the built-in shell code in the __DATA__ section, e.g.

  svn_test = test -d "$MR_REPO"/.svn
  git_test = test -d "$MR_REPO"/.git

(b) lib/git-fake-bare, e.g.

  git_fake_bare_test =
          test -d "$MR_REPO"/refs/heads && test -d "$MR_REPO"/refs/tags &&

(c) lib/vcsh, e.g.

  vcsh_test =
          test -d "$MR_REPO"/refs/heads && test -d "$MR_REPO"/refs/tags &&

I have audited all uses and cannot see any which depend on the
trailing slash being there.
