Fix the following uclibc build failure raised since bump to version 3.6
in commit 5f7275787ab1520c3d3f7eb9d2bd1b9f5ff41443 and
https://github.com/SELinuxProject/selinux/commit/cb8289c2b237e5f66e4a7608ecc6c68abeaeaf55:

selinux_internal.c: In function 'reallocarray':
selinux_internal.c:25:29: error: 'SIZE_MAX' undeclared (first use in this function)
   25 |         if (size && nmemb > SIZE_MAX / size) {
      |                             ^~~~~~~~
selinux_internal.c:6:1: note: 'SIZE_MAX' is defined in header '<stdint.h>'; did you forget to '#include <stdint.h>'?
    5 | #include <string.h>
  +++ |+#include <stdint.h>

selinux_internal.c:25:29: note: each undeclared identifier is reported only once for each function it appears in
   25 |         if (size && nmemb > SIZE_MAX / size) {
      |                             ^~~~~~~~
