Bug description:
  After isc-dhcp update from 4.3.5 to 4.4.1, dhclient-script uses
  valid_lft option when adding an IPv4 address.

  When used on the initrd generated by initramfs-tools, this will fail
  because busybox ip does not support this option.

  This affects the use of cloud-initramfs-dyn-netconf and ip= command
  line option, which breaks initramfs-tools testing.
