benchmarks: use %debug consistently among grammars.

Browse Source 
* etc/bench.pl.in (generate_grammar_triangular): Do not activate
%debug by default.  It can affect the timings even if yydebug=0.
(generate_grammar_calc): For consistency with other grammars,
use YYDEBUG environment variable to set yydebug.
