package/dhrystone: fix build with GCC 14.x

GCC14 will give errors for missing function declarations and
missing return types :

dhry_1.c:75:1: error: return type defaults to ‘int’ [-Wimplicit-int]
   75 | main(int argc, char *argv[])
      | ^~~~
dhry_1.c: In function ‘main’:
dhry_1.c:159:5: error: implicit declaration of function ‘Proc_5’ [-Wimplicit-function-declaration]
  159 |     Proc_5();
      |     ^~~~~~

Fixes:
