Change parameters of SO_VM_SOCKETS_* to uint64_t so that they are always

In include/uapi/linux/vm_sockets.h we talk about "unsigned long long",
but in the kernel code we use u64. IIUC "unsigned long long" should be 
u64 on every architecture, at least till we will have some 128-bit cpu, 
right?

I'm not sure what "unsigned long long" would be on a 128-bit machine.

What about using `unsigned long long` as documented in the vm_sockets.h?

I use uint64_t because the kernel uses u64. I think, this way the code
isn't vulnerable to potential variability of "unsigned long long".
If we change to "unsigned long long" should we also change the kernel
to "unsigned long long"?
