Make sure telemetry reporting is disabled in Tor Browser 9

We explicitly unset telemetry reporting for mobile and have this disabled for desktop as well.

We should double-check this for Tor Browser 9, though, as MOZ_TELEMETRY_REPORTING gets now automatically set for builds using official settings (as we do), see https://bugzilla.mozilla.org/show_bug.cgi?id=1549886.

I don't see any telemetry that is not already disabled by the prefs, but there's unnecessary code that is removed on build time when MOZ_TELEMETRY_REPORTING=0, and also it disables the telemetry section in about:preferences, making it impossible to enable. So I think it's good to have:

Thanks! Indeed, that's a good idea. I merged your tor-browser-build patch to master (commit 44d7ffc62c3df306a5e85d80d7607586f9c4d677). Could you make a !squash commit for tor-browser so we have all .mozconfig changes in one commit (af61067a0670be7c6a50ecd45ed062f2638ca9bc is the one on tor-browser-68.1.0esr-9.0-2 doing that currently)?
