Adapt AppArmor profile for Tor browser 13.0

Fix path variables in AppArmor profile

It is unclear to me what this is about.

We already allow ptrace for its relevant subprocesses via ptrace
rules, and I'm unsure if the full capability is really needed. I see
lots of other profiles which have ptrace rules without the capability
so I guess not. And I wonder if allowing the capability allows ptrace
for arbitrary processes, which would be really bad.

So let's assume it's not needed and we'll see what happens.

Firefox adjusts the OOM scores of its processes so that if they are
reaped they are killed in a sane order, e.g. the parent process last.
