sd-dhcp6-client: Add test case for Advertise message parsing
Add a basic test case excersising once more option parsing function in addition to lease handling. Check that the address iteration functions return the correct IPv6 address and lifetimes and that only one address is returned. Also verify that the server ID and preference values are read correctly.
