services/device/devicex: use sudo+su rather than just sudo -u
When the device manager is being installed in multi-user mode
use sudo+su to switch to the device manager user rather than
sudo -u, because the latter is often set up to require a password
on common GCE and EC2 images, whereas the former does not.
This does not break any jenkins tests, and it appeared not to
break
v23 go test -v v.io/x/ref/services/device --v23.tests --deviceuser=testdm --appuser=testapp
