Tom Tung 57e6375fc2 Bug 1696111 - Use sniffers in the requested category; r=necko-reviewers,valentin
After applying D102448,
uriloader/exthandler/tests/mochitest/test_nullCharFile.xhtml starts to fail.
The reason is that it adds image sniffer into net-content-sniffers which is not
expected.

Such that, this patch
- adds two other sniffers category:
  - orb-content-sniffers
    - The sniffers that are needed in ORB.
  - net-and-orb-content-sniffers
    - The sniffers that are in either orb-content-sniffers or net-content-sniffers.
- changes the way to ensure we only use the sniffers in the
requested category.
