[PATCH skeleton] skeleton: Update setValue() method dbus object '/org/openbmc/sensors/host/OccStatus'

[OpenBMC Patches]

From: Yi Li <adamliyi at msn.com>

In recent occ_i2c driver, a new hwmon sysfs attribte
'/sys/class/i2c-adapter/i2c-X/X-0050/online' has been used to
instantiate occ_i2c device. Update the 'OccStatus' dbus object
to use the new interface.
Do not use '/sys/class/i2c-adapter/i2c-X/new_device' anymore.
