Make DAV and SVN tests skip some svnauthz tests.
Make DAV and SVN tests skip some svnauthz tests.

I'll be refactoring them so not so many tests should get skipped but
for now make the build bots happy.

* subversion/tests/cmdline/svnauthz_tests.py
  (svnauthz_validate_test, svnauthz_accessof_test, svnauthz_accessof_is_test,
   svnauthz_compat_mode_test): Skip these tests unless doing an ra local test.
