Fix ScaleIO commands in rootwrap filters
Fix ScaleIO commands in rootwrap filters

Currently the ScaleIO command entry in compute.filters is this:
drv_cfg: CommandFilter, /opt/emc/scaleio/sdc/bin/drv_cfg, --query_guid,
root

During CI testing, we found that it should be changed to the following:
drv_cfg: CommandFilter, /opt/emc/scaleio/sdc/bin/drv_cfg, root,
/opt/emc/scaleio/sdc/bin/drv_cfg, --query_guid
