Subject: [PATCH] test_require.rb: clear load path

* test/ruby/test_require.rb (test_require_invalid_shared_object),
  (test_require_too_long_filename, test_require_changed_current_dir),
  (test_require_not_modified_load_path, test_require_changed_home),
  (test_require_to_path_redefined_in_load_path),
  (test_require_to_str_redefined_in_load_path),
  (assert_require_with_shared_array_modified): clear preset load path
  so that unexpected files will not get loaded.
