Display the relevant authz ruleset if an authz test in repos-test fails.

This makes it easier to diagnose test failures.

* subversion/tests/libsvn_repos/repos-test.c
  (authz_check_access): Add 'authz_contents' parameter. Display authz file
   contents in the generated error message when a test fails.
  (authz, test_authz_wildcards, test_authz_prefixes,
   test_authz_recursive_override, test_authz_pattern_tests,
   in_repo_authz, in_repo_groups_authz, groups_authz): Update callers.
