Fix the following build failure with uclibc < 1.0.35 raised since bump
to version 3.8 in commit 1f89c80417:
In file included from ./sys/random.h:40,
from getrandom.c:22:
/home/giuliobenetti/autobuild/run/instance-0/output-1/host/x86_64-buildroot-linux-uclibc/sysroot/usr/include/sys/random.h:27:35: error: unknown type name 'size_t'
27 | extern int getrandom(void *__buf, size_t count, unsigned int flags)
| ^~~~~~
/home/giuliobenetti/autobuild/run/instance-0/output-1/host/x86_64-buildroot-linux-uclibc/sysroot/usr/include/sys/random.h:8:1: note: 'size_t' is defined in header '<stddef.h>'; did you forget to '#include <stddef.h>'?
