meta-ethanolx: Enable ipmitool sol functionality

To enable Serial-Over-LAN functionality via the standard "ipmitool sol"
command it is necessary to create a DBUS interface
"xyz.openbmc_project.Ipmi.SOL" that would be used for the communication
between the "phosphor-net-ipmid" and "phosphor-host-ipmid"
applications.
