[PATCH v2 2/2] testsuite: add test for rootfs sstate

[Aliaksei Karpovich <akarpovich@ilbers.de>]

This test should catch the bug when user builds the same image
multiple times, adds and removes some package in image, but this
package is stayed on rootfs after removing.
The root cause is in sstate for rootfs.

Test conatins 3 build steps:
 1. Build the target
 2. Add some package in image and build the same target
 3. Remove package from image (return back to state in step 1) and
build the target again.

After each step, the test checks for the presence or absence of
the package on the rootfs.
