software/plantuml: move to python3

The only change to support python3 in software/plantuml is the move
from hexagonit to slapos download recipe in component/tomcat.
We also move the test to python3 by using plantuml egg v0.3.0. As this
egg doesn't support python2, the test is not done anymore in Python2.
