catch the execption during buildSensors

If there any sensor is being created or deleted,
the buildSenosrs will throw exceptions and the application will crash.
Add a retry logic to catch such exception and try again,
will quit the process finally if failed more than 5 times.

Tested:
Changing the PSU sensor threshold using ipmi commands,
no pid service crash log.
