[Buildroot] [PATCH] python: enabled IPv6 socket support

[Vanya Sergeev]

From: vsergeev <vsergeev at gmail.com>

Modified python package Makefile to pass the configure option for IPv6 socket
support if BR2_INET_IPV6 is set. Added patch to disable buggy_getaddrinfo test
during configure when cross-compiling.
