[PATCH skeleton] skeleton: add a new dbus method System::getFRUArea(fru_id)

[OpenBMC Patches <openbmc-patches@stwcx.xyz>]

From: Yi Li <adamliyi@msn.com>

This method will be used by ipmi-fru-parser to get fru area names defined
in ID_LOOKUP table. The ID_LOOKUP table defines FRUs that should be
present in the system.
