On a host without IPv6, socket(AF_INET6) fails with EAFNOSUPPORT, so
guest_sce_net aborted at its first IPv6 socket and never ran the TCP,
UDP, epoll, sendmsg/recvmsg, resolver and NetCtl checks after it.
When sceNetSocket reports guest EAFNOSUPPORT (47) for the IPv6 socket,
skip those socket checks, run the rest of the test, and exit with 77,
which ctest reports as skipped. Hosts with IPv6 run every check.
