Test IPv6 in alpha mobile releases once we have 0.4.x available there
In legacy/trac#29641 (moved) we set ClientAutoIPv6ORPort 1
to test IPv6 support in the alpha series. It needs tor 0.4.x, thus we need to wait until we can test it on mobile as well. (legacy/trac#30380 (moved) has another feature we want to test that depends on 0.4.x being available in mobile).
