Subject: fixes #1496 Provide NNG_ENABLE_IPV6 option (disabled by default)

This also checks if the build system has the definitions for AF_INET6, which might
help in some embedded IPv4 only settings.

The resolver test is enhanced to include a check for IPv6 enabled in the kernel.

IPv6 support is enabled by default, of course.
