Fix IPMI FRU editable field detection for abbreviated ipmitool names

ipmitool fru print on some BMC implementations returns short names
("Chassis Serial", "Board Mfg", "Board Product", "Board Serial",
"Product Serial") instead of the full names in the vendor doc.
Add both variants to fruEditableFields so all fields are editable
regardless of which naming convention the BMC uses.
