[PATCH] virNetSocketCheckProtocols: handle EAI_NONAME as IPv6 unavailable

[Guido Günther <agx@xxxxxxxxxxx>]

When running the test suite using "unshare -n" we might have IPv6 but no
configured addresses. Due to AI_ADDRCONFIG getaddrinfo then fails with
EAI_NONAME which we should then treat as IPv6 unavailable.
