    ioctl_pidfd02.c: fix clone3 EFAULT in 32-bit compat mode due to sign extension
    
    Correct the 32-bit pointer u64 conversion for args->pidfd. Direct
    casting from a 32-bit pointer to a 64-bit integer was causing incorrect
    sign-extension. Using (uint64_t)(uintptr_t) ensures a valid zero-padded
    64-bit address.
