    crunchgen(1): Fix compilation warnings (prepare for future update)
    
    Fix the following compilation warnings when we enable WARNS for
    initrd/{rescue,rescue.libcrypto} build in the future:
    
    ```
    rescue.c: In function 'cmpstringp':
    rescue.c:88:20: error: cast discards 'const' qualifier from pointer target type [-Werror=cast-qual]
      const char *s1 = *(const char **)p1;
                        ^
    rescue.c:89:20: error: cast discards 'const' qualifier from pointer target type [-Werror=cast-qual]
      const char *s2 = *(const char **)p2;
                        ^
    rescue.c: In function 'crunched_usage':
    rescue.c:96:1: error: old-style function definition [-Werror=old-style-definition]
     crunched_usage()
     ^~~~~~~~~~~~~~
    cc1: all warnings being treated as errors
    ```
