Anna Henningsen	7922830087	stream: fix `Writable` subclass instanceof checks `2a4b068aca` introduced a regression in where checking `instanceof` would fail for `Writable` subclasses inside the subclass constructor, i.e. before `Writable()` was called. Also, calling `null instanceof Writable` or `undefined instanceof Writable` would fail due to accessing the `_writableState` property of the target object. This fixes these problems.

stream: fix `Writable` subclass instanceof checks

2a4b068aca introduced a regression in where checking
`instanceof` would fail for `Writable` subclasses inside the
subclass constructor, i.e. before `Writable()` was called.

Also, calling `null instanceof Writable` or
`undefined instanceof Writable` would fail due to accessing the
`_writableState` property of the target object.

This fixes these problems.

stream: proper `instanceof` for `Writable`s

Use `[Symbol.hasInstance]()` to return `true` when asking for
`new Duplex() instanceof Writable`.
