ibm-read-vpd: Enable skipping VPD read if host is powered ON

This commit keys off of a JSON attribute on the FRU that enables the
parser code to skip reading VPD when the host is powered ON.

On IBM systems, certain FRU VPD is inaccessible to the BMC when the host
is powered ON. This commit enables us to skip such FRUs.

It relies on the xyz.openbmc_project.State.Chassis.CurrentPowerState
property to determine the host power state.

Tested: Tested on Rainier simulation model by manually setting the above
property and ensuring that VPD reads are skipped if the FRU contains
the "powerOffOnly" key in the JSON.
