drools-karaf-itest: don't override karaf version

 * the karaf version is coming from ip-bom. In case
   we need to override it for some reason we need
   to do that in kie-parent-with-dependencies so
   it is visible and shareable between all module modules
drools-karaf-itest: fix formatting in pom.xml
drools-karaf-itest: remove no longer needed plugin config

 * this seems to be some old config or maybe copy/paste
   error. The referenced file ${basedir}/replace-tokenFile.txt
   does not even exist so the plugin appears to be useless.
Fix typo OSGI -> OSGi
drools-karaf-itest: remove <repositories> specified in pom.xml

 * the repositories should not be specified here.
   JBoss.org repo is defined in the repo parent, that
   should be enough in case the parent chain was not built
   locally
