Subject: Mount vhost_sockets directory for vhost-user socket creation

For DPDK, vhost-user sockets are created on the host at
/var/lib/vhost_sockets directory, which will be used by
libvirt and openvswitch. This directory has the necessary
permissions and SELinux policies. Mount this folder for
libvirt container.

Partial-Bug: #1712732
(cherry picked from commit 3ea04744c22ae4cd2e1f2b77fc7d5ade012899e0)
