Historically, if we found an interface with an IPv6 address we
did not blindly trust that host is IPv6 capable (as in we can
successfully translate IPv4 addresses) but used getaddrinfo() to
confirm it. Turns out, we have use the same argument for IPv4.
For instance, in an namespace created by the following steps,
getaddrinfo("127.0.0.1", ...) fails (demonstrating by "Socket
TCP/IPv4 Accept" test case failing in virnetsockettest):
unshare -n
ip link set lo up

The virNetSocketCheckProtocols() function is supposed to tell
caller whether IPv4 and/or IPv6 is supported on the system. In
the initial round, it uses getifaddrs() to see if an interface
has IPv4/IPv6 address assigned and then to double check IPv6 it
uses getaddrinfo() to lookup IPv6 loopback address. Separate out
this latter code because it is going to be reused.
Since the original code lived under an #ifdef and the new
function doesn't it is marked as unused - because on some systems
it may be so.

This allows keeping a deterministic MAC address which can be useful for
