add4b0ab8c introduced a regression from Node 8 to Node 9 by removing the
`ArrayBuffer.isView(chunk)` check in `Zlib.prototype._transform` without
properly forcing `opts.objectMode` to `false` in the constructor because
the change to `opts` occurs after `opts` has been passed to the
`Transform` constructor. This commit fixes the issue by moving the call
to `Transform` after the changes to `opts`.
The regression can be demonstrated by running
node -e 'require("zlib").Gunzip({objectMode: true}).write({})'
On Node 8 this correctly throws a `TypeError`:
events.js:183
throw er; // Unhandled 'error' event
^
TypeError: invalid input

On Node 9 this causes an assertion failure:
