    fix get_placement function to use ps and new cgroup path

    Change in path to cgroup that has vcpu placement
    information is required for the function to work properly
    when run on host VM with Ubuntu 14. This breaks this
    function run in a docker container where cgroup paths
    are different. get_placement function now uses
    ps instead of pgrep due to fact pgrep was picking
    up more than qemu/VM process - it was not filtering
    '/bin/sh pgrep...' line.
