Updated spec to deal with renaming of cp tomcat in f19

So in F19 -> Its candlepin-tomcat
F18, Rhel 6-> Its candlepin-tomcat6
Also updated comps files and removed references to candlepin-jboss.
Something that used to be required but now not necessary.
Merge pull request #2877 from parthaa/candlepin-tomcat-spec-change
