David Brazdil 5ebb9947b4 selinux: vsock: Set SID for socket returned by accept() 
[ Upstream commit 1f935e8e72ec28dddb2dc0650b3b6626a293d94b ]

For AF_VSOCK, accept() currently returns sockets that are unlabelled.
Other socket families derive the child's SID from the SID of the parent
and the SID of the incoming packet. This is typically done as the
connected socket is placed in the queue that accept() removes from.

Reuse the existing 'security_sk_clone' hook to copy the SID from the
parent (server) socket to the child. There is no packet SID in this
case.
