udhcpc6: generate a consistent IAID

Currently, udhcpc6 does not meet the requirements for
Identity Association in RFC 3315.
This is a specific explanation in RFC 3315 protocol:
https://datatracker.ietf.org/doc/html/rfc3315#section-10
"The IAID uniquely identifies the IA and must be chosen to be unique
   among the IAIDs on the client.  The IAID is chosen by the client.
   For any given use of an IA by the client, the IAID for that IA MUST
   be consistent across restarts of the DHCP client."
This patch makes the client generate a consistent IAID based on the MAC address.
