If the kernel has IPv6 support then wget tries to create sockets using
AF_INET6 and then gets an EAFNOSUPPORT error, which it treats as a
connection failure, resulting in wget not being able to work. This patch
makes it switch it's default protocol to IPv4 when it sees that IPv6 isn't
supported in the kernel.
