RFR: 8299748: java/util/zip/Deinflate.java failing on s390x [v7]

[Amit Kumar]

> DeInflate.java test fails on s390x platform because size for out1 array which is responsible for storing the compressed data is insufficient. And being unable to write whole compressed data on array, on s390 whole data can't be recovered after compression. This PR updates the check method in the DeInflate test to no longer rely on pre-defined lengths/sizes to determine whether deflate followed by an inflate of data worked correctly. These sizes can vary depending on the underlying zlib implementations. The updated check method now uses a `ByteArrayOutputStream` to deflate into and then inflate from.
