yacc.c, lalr1.cc: fix warnings about yynerrs
Most often yynerrs is not used. Clang 15 now complains about such
variables. Bison itself does not compile:
```
src/parse-gram.c:1797:9: error: variable 'gram_nerrs' set but not used
[-Werror,-Wunused-but-set-variable]
int yynerrs = 0;
^
src/parse-gram.c:79:25: note: expanded from macro 'yynerrs'
^
1 error generated.
```
Reported by Nikita Popov.
Fixes https://github.com/akimd/bison/issues/89.
* data/skeletons/yacc.c (yynerrs): Flag with YY_ATTRIBUTE_UNUSED.
* data/skeletons/lalr1.cc (yynerrs_): Likewise.
