Do not generate a dist archive to jdk7 

Our distribution archive is supposed to contain all the original
sources, as well as derived architecture-independent files needed
for bootstrapping. So there should only be one distribution archive,
not a separate one for jdk7, especially, as the project is moving
away from java 7 soon. Change our artifact building accordingly.
Closes #2250.
