I don't think you need any new code in Catalog.pm, I believe the
suggestion was just to use that module as a stable interface to the
data. Looking at your patch, I'll mention that we have an idiom for
extracting #define'd OID symbols, e.g.:

my $FirstBootstrapObjectId = Catalog::FindDefinedSymbol(
'access/transam.h', \(at)include_path, 'FirstBootstrapObjectId');

This is preferred over using awk, which would have its own portability
issues (Windows for starters).

While I'm thinking out loud, it might be worthwhile to patch genbki.pl
for the duplicate test, since they're run at the same time anyway (see
catalog/Makefile), and we've already read all the data.
