git-svn: drop support for `--preserve-merges`

We already passed the `--rebase-merges` option to `git rebase` instead, now we make this move permanent. As pointed out by Ævar Arnfjörð Bjarmason, in contrast to the deprecation of `git rebase`'s `--preserve-merges` backend, `git svn` only deprecated this option in v2.25.0 (because this developer missed `git svn`'s use of that backend when deprecating the rebase backend running up to Git v2.22). Still, v2.25.0 has been released on January 13th, 2020. In other words, `git svn` deprecated this option over one and a half years ago, _and_ has been redirecting to the `--rebase-merges` option during all that time (read: `git svn rebase --preserve-merges` didn't do _precisely_ what the user asked, since v2.25.0, anyway, it fell back to pretending that the user asked for `git svn rebase --rebase-merges` instead). It is time to act on that deprecation and remove that option after all.
