Use CLOCK_BOOTTIME for default sensor implementation

Browse source 
The sensor implementation used to generate periodic signals according to
CLOCK_REALTIME. The clock can be adjusted by user or synchronization
service and results in wrong period. This commit changes it to
CLOCK_BOOTTIME which is monotonic.
