shill: support for DHCPv6 over PPPoE

Start a DHCPv6 configuration client for PPPoE virtual interface
if the interface is enabled for DHCPv6 when PPP connection is
established.  Use the generic file name (based on the interface
name) for the acquired lease, so that the lease file will be removed
when PPP connection is terminated.

This allows shill to obtain DHCPv6 configurations such as prefix
delegation ovet PPPoE.
