meta-openpower: move some metadata to machine conf

Install the openpower-ipmi-oem whitelist.

It is not currently installed because the ipmid recipe looks for
whitelists in VIRTUAL-RUNTIME_phosphor-ipmi-providers and
openpower-ipmi-oem is not set there.   Move
VIRTUAL-RUNTIME_phosphor-ipmi-providers += openpower-ipmi-oem to the
machine configuration so that the whitelist is detected by the ipmid
recipe and installed.
