Subject: [PATCH] The Zlib::GzipReader in JRuby does not behave as expected
 with REXML, so the test is skipped

## Why?

JRuby's `Zlib::GzipReader#readline` does not support arguments, so when using `Zlib::GzipReader.open`,
it always returns an empty string and does not function.
We will temporarily exclude `Zlib::GzipReader` from test coverage.

```
$ test/run.rb --location test/test_order.rb:49

Failure: test_more_ordering(REXMLTests::OrderTester)
/Users/naitoh/ghq/github.com/naitoh/rexml/test/test_order.rb:110:in `test_more_ordering'
     107:          count += 1
     108:        }
     109:
  => 110:        assert_equal( actual.size, count )
     111:      end if defined?(Zlib::GzipReader)
     112:   end
     113: end
<46> expected but was
