[ruby/zlib] Fix setting mtime to zero in GzipWriter
Before this change, it was not possible to write out zero for the timestamp part of a Gzip file's header, as calling GzipWriter#mtime with zero was ignored. Judging from the docs for `GzipWriter#mtime=`, it should be possible to indicate that no timestamp is available by calling the method with zero. https://github.com/ruby/zlib/commit/310be39cac
