This reverts commit 4f3aafa1e4.
Once merged upstream, the CI failed here with:

We are figuring it out but revert this so we can release an alpha.
Previously we would incorrectly detect that ipv6 isn't supported if the
ping binary isn't present (as it may not be in a relatively stripped
down container image), or if ICMP packets aren't permitted (as they
often aren't in containers).
We don't really have a need to run these network tests on non-IPv6
systems, so it makes more sense to just run them unconditionally.
While chutney currently runs tor's chutney test in its own CI,
it's difficult to guarantee the two won't accidentally diverge.
Probably best to use a fixed version here so that we can control
chutney version bumps and avoid surprise breakage in tor's CI.
This will also free us to intentionally make breaking changes in
chutney (though I don't have any immediate plans for any).
Conflux circuit building was ignoring the "predicted ports" feature,
which aims to make Tor stop building circuits if there have been
no user requests lately. This bug led to every idle Tor on the
network building and discarding circuits every 30 seconds, which
added overall load to the network, used bandwidth and battery from
clients that weren't actively using their Tor, and kept sockets open
on guards which added connection padding essentially forever.
Bug went in on commit 39c2927d when we added preemptive conflux circuit
pools.
Fixes bug 40981; bugfix on 0.4.8.1-alpha.
Resources allocated by cpuworker weren't being freed on clean shutdown.
This applies for worker threads, worker thread pool, reply queue, reply
event, ...
