test/rdoc: avoid tempfile leaks

* test/rdoc/test_rdoc_parser.rb (test_class_for_forbidden): avoid
  tempfile leaks by using `Tempfile.create` instead of
  `Tempfile.open`.
* test/rdoc/test_rdoc_rd_block_parser.rb (test_parse_include_subtree):
  ditto.
* test/rdoc/test_rdoc_rdoc.rb (test_parse_file_encoding): ditto.
* test/rdoc/test_rdoc_rdoc.rb (test_parse_file_forbidden): ditto.
