teor (Tim Wilson-Brown) 86eba14ac5 Fix unit tests on systems without IPv4 or localhost addresses

Make unit tests pass on IPv6-only systems, and systems without
localhost addresses (like some FreeBSD jails).

Fixes:
* get_if_addrs_ifaddrs: systems without localhost
* get_if_addrs_ioctl: only works on IPv4 systems
* socket: check IPv4 and IPv6, skip on EPROTONOSUPPORT
* socketpair_ersatz: uses IPv4, skip on EPROTONOSUPPORT

Fixes bug #17632; bugfix on unit tests in 0.2.7.3-rc.
c464a36772 was a partial fix for this issue in #17255;
it was released in unit tests in 0.2.7.4-rc.
