[systemd] Make sensorfwd wait for oneshot-root.service. Fixes JB#41619

Android services/actions launched by droid-hal-init, queued oneshot
scripts and sensorfwd are executing in parallel during bootup. During
especially the 1st boot the scheduling of tasks can lead to sensorfwd
getting hold of nonfunctional sensor hal.

Delaying sensorfwd startup until oneshot scripts have been executed
makes it less likely for the problem to surface.
