rpcbind: fix build on toolchains without IPv6 support

From ab7769e4b57741c654f1a815b006d6548104ba95 Mon Sep 17 00:00:00 2001

From: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

Subject: [PATCH] Make IPv6 configurable

Add an autoconf check that verifies whether IPv6 is available or not,

and define the INET6 macro if available, instead of hardcoding it in

src/Makefile.am.
