[PATCH v2] lib/igt_sysfs: update igt_sysfs_engines to run dynamic tests with its associated engine class.

From: Sai Gowtham Ch <sai.gowtham.ch at intel.com>

Correlate updates in sysfs engines queried and the work load submitted
to a engine, enhancing igt_sysfs_engines so that each update in sysfs
engine will corelates to it corresponding engine class.
