[PATCH] selftest/manifest.py: Test to verify rootfs manifest

[Benjamin Esquivel <benjamin.esquivel@linux.intel.com>]

Adding a new test to verify if the packages in the
manifest files actually exists in pkgdata.
 -adding a setUpClass for when more tests get created here
 -check for the paths and fail gracefully if not there
 -skip the test when there are no manifest files to check
 -debug prints for failure analysis
