This reverts commit bf2a399f

.

Don't set by default the prefer IPv6 feature on client ports because it breaks
the torsocks use case. The SOCKS resolve command is lacking a mechanism to ask
for a specific address family (v4 or v6) thus prioritizing IPv6 when an IPv4
address is asked on the resolve SOCKS interface resulting in a failure.

Tor Browser explicitly set PreferIPv6 so this should not affect the majority
of our users.

Closes #33796
