deps: cherry-pick bfbe4e38d7 from libuv upstream

Original commit message:
  aix: disable ipv6 link local (#4229)

  AIX does not implement ifaddrs and when retrieving the network
  interfaces with uv_interface_addresses there was a test failure in
  tcp_connect6_link_local.

  For now disable ipv6 link local on aix to:

  1) fix broken aix build
  2) stop blocking libuv upgrade in node
