During the bootstrap data format conversion, it seemed important for
verifiability's sake that the generated postgres.bki file stayed the same
as before. That resulted in adding a bunch of ad-hoc rules about when to
quote emitted data values, to match previous manual decisions that had
often quoted values unnecessarily. Now that the conversion is complete,
it seems fine to remove all those ad-hoc rules. The net actual effect on
the current contents of postgres.bki is that some fields that had been
quoted despite containing only digits or only "-" lose their unnecessary
quotes.
Also, now that genbki.pl will always quote values containing a backslash,
there's no need for bootscanner.l to allow unquoted octal escapes;
so simplify its production for "id" by removing that possibility.
