[PATCH] chassis_id: clean compilation and fix bad function parameter passing

Adding prototypes for functions resulted in an error, cause:
  table_find_disk(disk_snum, &chassis_num, &slot_num);

is called but the function is defined as:
  int table_find_disk(char *serialnumber , int *host_num, int *chassis_num, int *slot_num)

which can obviously not work correctly.

Using popen() is not klibc compatible, so skip the compilation if
a klibc compile is requested.
