Remove the Firefox-specific 'read with streaming' unit-test

Browse Source 
Support for the non-standard `moz-chunked-arraybuffer` response type is in the process of being removed from Firefox; see e.g. https://bugzilla.mozilla.org/show_bug.cgi?id=1411865

For the time being, you probably want to keep support for this in the general PDF.js library given that feature detection is used. However, removing the unit-test immediately seems reasonable, since it will otherwise start failing once the platform support for `moz-chunked-arraybuffer` is gone.

Fixes 8851; please note that if unit-tests for the code in `fetch_stream.js` are wanted, which I'm assuming they are, those should live in their own file rather than being lumped into `network_spec.js` anyway.
