With this update we need to rebase the nix_plugin_paths patch, which was
done by @srp and I took it from his comment at:
https://github.com/NixOS/nixpkgs/pull/15762#issuecomment-222230677
Other than that, using libjpeg from nixpkgs fails to link:
https://headcounter.org/hydra/build/1114273
Rather than just using versionAtLeast to check for >= version 52, we're
matching on the explicit version number. That way we can make sure that
we (try to) build with system libjpeg again so we can keep it out of the
overall Chromium build time.
Built and tested using the VM tests on my Hydra at:
