Also updated kNonUpdatedHeaders with more headers from the
nsHttpResponseHead file
Spec: https://fetch.spec.whatwg.org/#concept-http-network-or-cache-fetch
Spec issue: w3c/webappsec-csp#161
While the spec does not give any list of content headers that should be ignored
on a 304 request, some of them are directly dependent on the resource body and
as such should not be updated (for example
content-length
cannot be differentsince the content remains identical).
The exact list of ignored headers is identical to the one that firefox uses.
