fix compiler warning and errors when compiling statmount test.

gcc 12.3 (Ubuntu 12.3.0-1ubuntu1~22.04)

statmount_test.c:572:24: warning: implicit declaration of function
‘offsetof’ [-Wimplicit-function-declaration]
  572 | #define str_off(memb) (offsetof(struct statmount, memb) /
sizeof(uint32_t))
      |                        ^~~~~~~~
statmount_test.c:598:51: note: in expansion of macro ‘str_off’
  598 |         test_statmount_string(STATMOUNT_MNT_ROOT,
str_off(mnt_root), "mount root");
      |
^~~~~~~
statmount_test.c:18:1: note: ‘offsetof’ is defined in header
‘<stddef.h>’; did you forget to ‘#include <stddef.h>’?
   17 | #include "../../kselftest.h"
