Add platform name to output archives for products

This works for a single platform, but not sure if it will work for
multiple (depends if there is exclusivity of profiles in the naming of
the file).

I can't easily test multiple on my machine (issues in .AU P2 repos) --
we can revert if this doesn't work.
Correct for missing exit status in print and execute script
