git-svn: fix tests to work with older svn

Some of the recent changes and shortcuts to the tests broke
things for people using older versions of svn:

t9104-git-svn-follow-parent.sh:
  v1.2.3 (from SuSE 10.0 as reported by riddochc on #git
  (thanks!)) required an extra 'svn up'.  I was also able to
  reproduce this with v1.1.4 (Debian Sarge).

lib-git-svn.sh:
  SVN::Repos bindings in versions up to and including 1.1.4
  (Sarge again) do not pass fs-config options to the underlying
  library.  BerkeleyDB repositories also seem completely broken
  on all my Sarge machines; so not using FSFS does not seem to
  be an option for most people.
