Improve host state monitor

This changes to arg0 in the match to limit to just the State.Host
interface and looks just for the CurrentHostState property to
prevent errors printing for properties we don't care about.

It also moves the message.read into a try-catch since it can throw
and changes to get_if instead of get to reduce the number of
possible exceptions.

Tested:
Ran ipmitool power on/off and confirmed that the "Host system DC
power is on/off" message prints correctly without any spurious
error messages.
