We need to drop BuildArch: noarch now, since this is an arch-dependent path. Replace BuildArch: noarch with ExclusiveArch: aarch64.

Do that and add the following to the top of the spec:

# This package does not have anything to compile and have debug symbols
%global debug_package %{nil}

I think that the override should rather be added somewhere like https://searchfox.org/mozilla-central/source/browser/extensions/webcompat/data/ua_overrides.js

This needs to be rebased as it conflicts with mainline now.

As far as I'm concerned there is no legitimate reason to be sniffing architecture, and both Firefox Mac and Windows pretend to be x86 always, as does Chromium. Hence, I'd much rather spoof it across the board. It's not just YouTube, I've already gotten reports of other sites doing stupid stuff for ARM64.

Done and rebased.
