Tero Kauppinen 8cdc61b924 fix(kube-proxy): fix IPv6 support check for Linux ...

The current Linux implementation checks whether a node supports
IPv6 by testing for the presence of '/proc/net/if_inet6'. However,
that check does not confirm that IPv6 support is actually enabled.
As a result, kube-proxy can incorrectly enable dual‑stack support
on nodes that do not have IPv6 enabled.

The possibility to disable IPv6 support has existed since
Linux kernel v2.6.27.

Update the IPv6 support check to also consider the contents of
'/proc/sys/net/ipv6/conf/all/disable_ipv6'.
