Roman Bolshakov dbb5e20ede tests: Avoid IPv4-translated IPv6 address in sockettest 
getnameinfo on macOS formats certain IPv6 addresses as IPv4-translated
addresses. The following pattern has been observed:
  ::ffff is formated as ::0.0.255.255
  ::fffe is formated as ::0.0.255.254
  ::ffff:0 is formated as ::255.255.0.0
  ::fffe:0 is formated as ::255.254.0.0
  ::ffff:0:0 is formated as ::ffff:0.0.0.0
  ::fffe:0:0 is formated as ::fffe:0:0
  ::ffff:0:0:0 is formated as ::ffff:0:0:0

The getnameinfo behavior causes a failure for:
  DO_TEST_PARSE_AND_FORMAT("::ffff", AF_UNSPEC, true);

Use non-ambigious IPv6 for parse/format testing.
