Tor Browser fails to start on some Linux systems without libatomic being installed

E.g. Trisquel 8 32bit seems to be affected, ses this thread on our blog.

Our Tor Browser 8.5.5 worked on those systems, though.

It seems Icecat is still on 60esr, so any older systems that only have Icecat (or similar) installed won't have libatomic installed as a dependency yet (sigh).

I guess we can either bundle it (as a fallback) or try detecting this at run-time and notify the user they should install it.
