deb6f16d82 virtcontainers: update context id of vsock to uint64
The CID of VSock needs to be change to uint64. Otherwise that leads to
an endianess issue. For more details see
https://github.com/kata-containers/runtime/issues/947

Remove the uint64 introduced by #984

Fixes: #958

9b283254c3 virtcontainers: Implement function to get a free context ID
FindContextID generates a random number between 3 and max uint32
and uses it as context ID.
Using ioctl findContextID checks if the context ID is free, if
the context ID is being used by other process, this function
iterates from over all valid context IDs until one is available.

`/dev/vhost-vsock` is used to check what context IDs are free,
we need it to ensure we are using a unique context ID to
create the vsocks.
