zpcictl: include sys/sysmacros.h to avoid minor/major glibc warnings

The minor()/major() function definitions are moved to sys/sysmacros.h
and will be removed from sys/types.h.  To correct below warning, simply
include sys/sysmacros.h.

  zpcictl.c: In function ‘sysfs_get_slot_addr’:
  zpcictl.c:184:13: warning: In the GNU C Library, "major" is defined
   by <sys/sysmacros.h>. For historical compatibility, it is
   currently defined by <sys/types.h> as well, but we plan to
   remove this soon. To use "major", include <sys/sysmacros.h>
   directly. If you did not intend to use a system-defined macro
   "major", you should undefine it after including <sys/types.h>.
    major = major(dev_stat.st_rdev);
               ^~~~~~~~~~~~~~~~~~~~~
