tests: Show vm-run.sh command line for re-running failure sequences

Now that vm-run.sh supports a long list of test cases without crashing
the VM kernel, there is no need to use the "parallel-vm.py -1 1 <tests>"
workaround. Print the re-run example commands with vm-run.sh instead. In
addition, add the --long argument if it was specified for the test run
to avoid skipping test cases in the re-run case.
