lint: remove unnecessary '%prec T_COMMA' from grammar 

My previous commit message was wrong in saying that the '%prec' was
necessary.  It is not necessary.

Most probably I misspelled the name of the grammar rule as opt_comma
instead of comma_opt, which would lead to the same number of conflicts
in the grammar plus a warning, but no build failure.
