DEV300 masterfix: #i10000#: Some fixes for the new smoketest: solenv/inc/installationtest.mk used wrong variables (UPDMINOR is not set on RE master builds, use LAST_MINOR from minor.mk instead), smoketestoo_native/makefile.mk needed adaptions to new install set naming scheme.

DEV300 masterfix: #i10000#: deliver.pl: -zip -delete: skip directly to next zipfile also if the current one doesn't exist

sb118: backed out passing UNO_JAVA_JFW_ENV_JREHOME/CLASSPATH again; for one, those settings (partially pointing into solver) do not work to unopkg add an .oxt containing a .jar into the installation being created; for another, a fix for i77196 will probably obsolete a need to call unopkg during installation anyway; I assume I added this so that bogus ~/.ure settings do not prevent unopkg (and javaldx) from working here
