chassishandler: Interpret intrusion sensor values

Chassis Intrusion Sensor value on D-Bus was updated with new format that
adapts PDI enum definition [1]. This patch modifies how the value from
D-Bus be interpreted to adapt with the change from D-Bus. This commit
uses GetSubTree to look for all object paths that implement the
Chassis Intrusion interface, instead of using hardcoded path.
phosphor-dbus-interfaces class is used to ensure consistency.

When more than one path is returned from GetSubTree. If all the Status
values are Normal, the final result is inactive. If one of the Status
value is not Normal, the final result is active. If no Status value can
be read from D-Bus, the final result is inactive.

Tested:
If value on D-Bus is:
"xyz.openbmc_project.Chassis.Intrusion.Status.Normal"
$ ipmitool chassis status | grep -i intrusion
Chassis Intrusion: inactive

Otherwise, Chassis Intrusion: active
