Capture weak reference of sensor object in lambda

dbus callback methods are capturing 'this' pointer directly. A sensor
object can get deleted while a callback is pending invocation. This is
crashing ipmbsensor daemon.

Capture weak reference in place of this pointer.

Tested: Run ipmbsensor as a binary with entity manager constantly
restarting to simulated destruction and construction of new sensor
object. No crash was observed after running for three hours. Prior to
this ipmbsensor was crashing within one hour
