libtirpc: Support ipv6 in DISTRO_FEATURES

If the ipv6 feature for the distribution is not set, the package should not
contain settings for ipv6. This makes rpcbind doesn't try to bind to a IPv6
socket, and complain that this fails.

+Subject: [PATCH] netconfig: remove tcp6, udp6 on --disable-ipv6
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If the configuration for IPv6 is disabled, the netconfig should not contain
+settings for tcp6 and udp6.
+
+The test for the configure option didn't work, because it check the wrong
+variable.
