MINOR: quic: test IP_PKTINFO support for quic-conn owned socket
Extend the startup platform detection support test for quic-conn owned
socket. It is required to be able to retrieve destination address on a
recvfrom() system call so check if IP_PKTINFO or IP_RECVDSTADDR flags
are supported.
This change is part of quic-conn owned socket implementation.
It may be backported to 2.7 after a period of observation.
