sensors: get rid of com.samsung.permission.SSENSOR

Samsung uses a permission com.samsung.permission.SSENSOR
for Samsung-specfic sensors. Android obviously does not
have that and the default is denied when there is no
permission. As such, those sensors are inaccessible.

Thus, this change removes this permission from those sensors
so we can use them.

Android does not require special permissions for most sensors
so this change doesn't attach additional permission requirements
to those sensors.

However, note that it is possible that some sensitive sensors
introduced by Samsung in the future may use SSENSOR permission
and for privacy reasons they should be handled separately with
appropriate permission control attached.
