🔥 Remove update system patch

This is causing issues upstream (pulse-browser/browser#173). This wouldn't be an issue if mach respected overriding `@MOZ_APPUPDATE_HOST@`, but that does not appear to be the case. Instead, this patch should be handled by upstream users.

If anyone needs help migrating, open an issue or ping me in discord

-By defualt gecko will send a large amount of details to the server when
-deciding to update. This makes the gluon generation code significantly
-more complex, so we have just removed a large number of those
-paramaters. Maybe in the future, if we write our own server update
-software, we will add these back in to help with analytics
