ntp: set local address on PTP socket on FreeBSD

Browse source 
Fix the FreeBSD-specific code checking for a bound IPv4 socket to
include the new PTP port. This should fix a multihomed server to respond
to NTP-over-PTP requests from the address which received the request.

Fixes: be3158c4e5 ("ntp: add support for NTP over PTP")
