RFR: JDK-8190735: Define all base artifacts for all open/open-debug profiles

[Erik Joelsson]

When first defining artifacts for build profiles in Jib, I only defined 
those that we are actually publishing in promoted builds. With Mach 5 we 
now have requirements on being able to test open only builds as well as 
their debug variants.This patch removes the special case definitions of 
artifacts for the open and open-debug profiles and instead derives them 
from the main profiles. I also removed the no longer needed 
"compact-profiles" target from linux-x86-open.
