don't regression test when building the simulator package

we did the tests already when building the HA manager package so
if those did not fail the one from the HA manager simulator will
certainly not fail too so do not waste time running them again.

This has the small drawback that if anyone just builds the simulator
package through `make simdeb` the test won't be run at all for the
build package, this is seldom the case and can be worked around -
i.e. just use the all make target or run the tests manual.
