util/bincfg: cleanups: use static whenever possible

Some non-static declaration remains. If they were made
static, the compiler would output some warnings:
  bincfg.y:30:1: warning: useless storage class specifier in empty declaration
   };
   ^
  bincfg.y:47:1: warning: useless storage class specifier in empty declaration
   };
   ^
  bincfg.y:22:12: warning: ‘yylex’ used but never defined
   static int yylex (void);
              ^~~~~
  bincfg.y:456:13: warning: ‘set_input_string’ used but never defined
   static void set_input_string(char* in);
               ^~~~~~~~~~~~~~~~
