Set correct permissions for vhostuser sockets

The latest updates to DPDK in 16.04 and above introduce two new
parameters for DPDK initialization which avoid the need to run
qemu processes with vhostuser sockets as root.

Use these options to ensure that sockets are created with the
correct ownership and permissions for OpenStack/KVM.
