Subject: [PATCH] integration-cli: don't build -test images if they already
 exist

There's no need to try to re-build the test images if they already
exist. This change makes basically no difference to the upstream
integration test-suite running, but for users who want to run the
integration-cli suite on a host machine (such as distributions doing
tests) this change allows images to be pre-loaded such that compilers
aren't needed on the test machine.

However, this does remove the accidental re-compilation of nnp-test, as
well as handling errors far more cleanly (previously if an error
occurred during a test build, further tests won't attempt to rebuild
it).
