Smoke tests: declare the assembly deps. in approapriate profiles

 * having the dependencies at the top-level causes them to be
   downloaded even though they may not be required. For example
   when one wants to run the tests on Tomcat, only the tomcat7 wars
   are needed. However, so far all the kie-wb and kie-drools-wb
   wars were downloaded. From now on, the different
   deployables are declared in the respective profiles, so only
   the wars for particular container are downloaded.
