RFR: 8232024: Don't pollute log output with multiple errors of the same type

Wed Oct 21 17:10:17 UTC 2020

Don't run ldd and build list of dependency packages in case jpackage builds DEB package on non Debian Linux and RPM on Debian Linux. In this cases attempts to detect what packages provide libs will fail anyways, so don't waste time and pollute jpackage log output.
