shill: command line support for DHCPv6

Add command line option "--dhcpv6-enabled-devices" to enable DHCPv6
for specific devices.  The obtained DHCPv6 configuration is for
informational purpose only, will not be used to setup connection nor
update system configuration by shill.

Note: since shill does not use DHCPv6 configuration to setup any
connection, other IP configuration (DHCPv4 or IPv6 over RDNSS)
is required in order for the device to setup a connection for a
given network service.

BUG=chromium:492764
TEST=USE="dhcpv6 asan clang" emerge-$BOARD shill
TEST=USE="asan clang" emerge-$BOARD shill
TEST=Verify with new DHCPv6 client auotest
Manual Test:
1. Build/install IPv6 enabled dhcpcd and DHCPv6 enabled shill
2. Setup a virtual ethernet pair using:
   "ip link add name veth_master type veth peer name slave"
2. Setup a DHCPv6 server on veth_master interface
   "/usr/sbin/dhcpd -6 -cf /tmp/dhcp6.conf veth_master"
3. Start shill with DHCPv6 enabled for "slave" interface
4. Verify DHCPv6 configuration via
   "/usr/local/lib/flimflam/test/list-ipconfigs slave"
