Bug 1603160 - Allow MediaQueryList::AddListener to receive untrusted …

…events. r=bzbarsky

I was looking into MediaQueryList tests in the context of:

  w3c/csswg-drafts#4531

And this seemed reasonably easy to fix.

I don't see anything in:

  https://drafts.csswg.org/cssom-view/#dom-mediaquerylist-addlistener

Which doesn't mention anything about untrusted listeners.

I haven't investigated the remaining failure, it seems we call the capture
listener after the regular one...
