Add handling for FRU prefixes

There are some FRU eeproms in the wild that use the custom field to
represent the MAC address, but prefix the mac itself with "MAC:"

Detect this case, and expose this as a new field MAC_<Previous
fieldname>.  This allows Entity-Manager to properly parse the MAC
address to fill into EthernetInterface and set the MAC address.

Tested: Boot a platform with this type of fru (P3809)
Observe that the MAC address is set correctly.  Introspecting DBUS shows
the mac field was added correctly
