Remove creation of POLICY_HOME/etc/ssl

Remove creation of POLICY_HOME/etc/ssl

onap/policy-jdk-debian is only used by policy/drools
and policy/engine.  Their corresponding Dockerfiles
remove the precreated $POLICY_HOME/etc/ssl in order
to proceed with their images build.  In any case,
the directory layout under $POLICY_HOME should be handled
by its respective derived images.

Miscellaneous clean up of packages in the base image.
Some packages are only used in drools and not in engine,
hence removed and moved to drools.   The python dependencies
(python 2) created issues with tooling (http and telemetry).
