run-integration-tests: only do the clean operation in the beginning

When doing 'make clean', we remove the cached image. So doing
'make -C TEST-NN-foo clean setup run clean-again' in a loop is very slow.
Let's filter out the 'clean' target (if specified), and do the cleaning
in the beginning, and then run other targets in a loop as before.
