dbus-sensors: Change the host state match string

When the CurrentHostState dbus property value ends with "Running",
Dbus-sensors marks the host as running and starts reading the sensors
with "PowerState=On" configuration.
From commit "host state transitioning ...", phosphor-state-manager
package updates the transition state "TransitioningToOff" or
"TransitioningToRunning" to CurrentHostState property. This causes
dbus-sensors detects the host is running when it is transiting to
running state.
This commit fixs that issue by changing the match string from
"Running" to ".Running".

Tested:
	1. Power off the host.
	2. Power on the host.
	3. Make sure there is no threshold warnings/errors for
	the sensors with "PowerState=On" configuration.
