[PATCH skeleton v4] skeleton: fixed hard-coding of master OCC hwmon sysfs path for PowerCap object

[OpenBMC Patches]

Currently master OCC hwmon sysfs path is hardcoded to '/sys/class/hwmon/hwmon3/'.
This make the '/org/openbmc/sensors/host/PowerCap' interface cannot work when
master OCC is initilized as hwmon device other than 'hwmon3'.

'usr_powercap' attribute should be searched when OCC is active.
When skeleton creates 'PowerCap' objects, OCC may not be active.
So do the search each time setting power cap. Raise an exception when
there is no 'user_powercap' attribute.

This would fix the issue: https://github.com/openbmc/skeleton/issues/42

Also raise an exception when setting power cap fails. The exception
will be returned to REST API caller. This would fix the issue:
