fbc-debug: remove BINCL and EINCL STAB tags

- whitespace corrections
- ctx.filename is never used, so ucase(*filename) is unnecessary
- BINCL/EINCL appears to be intended to be used when the STAB type information is emitted for full headers.  fbc doesn't do this, it only emits the type information for types that are actually used.  In that sense, we are already emitting the least amount of type information possible.
- therefore BINCL/EINCL tags are removed as they were previously used in a way that was never intended by the STAB format
