fru_gen: eliminate unnecessary maps
The type of the generated fru data contained a map of a map of a map of a map, but for all except the outermost map, all elements were iterated over when using the map. Therefore, change them to a vector<pair<...>> instead. Vector should generate smaller code and allow faster iteration. Vector insert and iteration are both linear where as map is O(n lg n).
