gh-124228: Fix UUID configuration in configure files for NetBSD compatibility #124229

In NetBSD the py_uuid_generate_time_safe function generates a uuid using the uuid_create and uuid_enc_be functions. The uuid version generated is 4.

An example to reproduce the situation;

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <uuid.h>

int main() {
    uuid_t *uuid;
    unsigned char encoded_uuid[16];

    uuid = malloc(sizeof(struct uuid));
    if (!uuid) {
        fprintf(stderr, "Memory allocation failed\n");
        return 1;
    }

    uuid_create(uuid, NULL);
    uuid_enc_be(encoded_uuid, uuid);

    printf("Converted UUID: ");
    for (int i = 0; i < 16; i++) {
        printf("%02x", encoded_uuid[i]);
        if ((i == 3 || i == 5 || i == 7 || i == 9) && i < 15) {
            printf("-");
        }
    }

    printf("\n");
    free(uuid);

    return 0;
}
