sdm660-common: rootdir: Run sensors daemon as system user instead of root

Browse source 
Grant capabilities and change file permissions to allow the sensors.qcom
daemon to start up as the system user/group, rather than running as
root.

Fixes: 63775281
Test: monitor logcat after reboot, confirm no file open errors. Run
QSensorTest, confirm all sensors provide sane data. Confirm that
IMU calibration can read + write its saved settings. Run sensors CTS.
