gen_ipmi_fru.pl: construct FRU metadata

For IPMI FRUs, generate a file to depict which dbus properties are
implemented for a FRU, and what IPMI FRU properties those dbus
properties map to.

This commit defines a YAML file which helps figure out the supported
dbus inteface/properties for a FRU, and what the corresponding IPMI FRU
properties are.
