util/cbfstool: Revise lex/yacc (bison) generation

Revise the Makefile.inc rules for generating FMD parser files.

- lex:  If --header-file is supported then the lex (usually flex) should
        also support '-o' so we don't need to do redirection (-t).

- yacc: Bison is already required by bincfg and sconfig so we
        can change the default parser compiler to Bison. That also
	allows us to use -o and --defines to override the output files.

- both: Line directives are only helpful when debugging the scanner and
        the parser, so we should remove them to get better git diff
	results  (-L for lex, -l for bison).

Also regenerated the shipped files with latest version of flex (2.6.4)
and bison (3.8.2).
