upgrade to tor 0.4.8.8
Closes #20018 (closed)
Test #2 ( https://jenkins.tails.boum.org/job/test_Tails_ISO_20018-tor-0.4.8.8-force-all-tests/2/ ) showed 3 failed scenarios, I re-ran those in: #5 https://jenkins.tails.boum.org/job/test_Tails_ISO_20018-tor-0.4.8.8-force-all-tests/5/ #7 https://jenkins.tails.boum.org/job/test_Tails_ISO_20018-tor-0.4.8.8-force-all-tests/7/ Where they all succeeded. I guess that's good enough?
