Miroslav Lichvar b8b3830dc4 ntp: randomize address selection on all source replacements ...

If the resolver orders addresses by IP family, there is more than one
address in the preferred IP family, and they are all reachable, but
not selectable (e.g. falsetickers in a small pool which cannot remove
them from DNS), chronyd is unable to switch to addresses in the other IP
family as it follows the resolver's order.

Enable randomization of the address selection for all source
replacements and not just replacement of (unreachable) tentative
sources. If the system doesn't have connectivity in the other family,
the addresses will be skipped and no change in behavior should be
observed.
