fru_gen: reduce map in generated data

Eliminate one level of the generated "frus" map by creating
a structure for the lowest-level member.

This should reduce the impact of a gcc bug that consumes
excessive memory when compiling the generated map.  Also
removed the runtime calculation of the 'delimiter' character
and instead generated it in the fru_gen python script.

Resolves openbmc/openbmc#1441.
Resolves openbmc/openbmc#1166.
