[OPENJDK-2968] move ARGS/OPTS handling to run-java.sh

Move the handling of JAVA_OPTIONS, JAVA_OPTS and suffixing of
JAVA_ARGS onto the command line, as well as dispatching to an
application-supplied run script, from s2i/run to run-java.sh.

This is to make this logic available to the runtime images.
