tomcat8 is in extra seed because of *-examples

[Andreas Hasenack]

While removing authbind from the server-ship seed [1], we came across an unexpected (to us) dependency chain:

http://people.canonical.com/~ubuntu-archive/germinate-output/ubuntu.disco/rdepends/tomcat8/tomcat8-examples

tomcat8-examples
* Extra seed

shows that tomcat8 is in the extra seeds via tomcat8-examples, because of this in the "supported" file[2]:

supported: * Extra-Include: *-dbg *-debug *-dev *-doc *-docs gir1.2-* *-examples

We are not sure if this should be the case, so this bug is to discuss whether we should add an Extra-Exclude line for tomcat8-examples to the same file.

tomcat8 got remove from main, thereby no (other) binary from the same source is in main.
Due to that the source itself goes out of main and the wildcard no more applies.
Thereby -> fix released.
