issues mhagger#20: Make run-test.py possible to run on environments nowadays.

* svntest/__init__.py, svntest/actions.py, svntest/factory.py,
  svntest/main.py, svntest/objects.py, svntest/sandbox.py,
  svntest/testcase.py, svntest/tree.py, svntest/verify.py,
  svntest/wc.py:
    Update the svntest subdirectory from

      http://svn.apache.org/repos/asf/subversion/trunk/subversion/tests/cmdline/svntest

    using svntest/update.sh.  Adjust run-tests.py for changes in svntest.

* runtest.py:
  - Adjust required version of Python 2.
  - Get the minor version of installed svn program and set it to
    svntest.main.SVN_VER_MINOR. This allows at least Subversion >= 1.9
    to run the test suites.
