Allow full compiles on Java 8.

Make jgit.java6 and jgit.java7 activation based on ranges so modules in
jgit.java6 are enabled for Java 1.6+ and modules in jgit.java7 are
enabled for Java 1.7+. This enables full compiles on Java 8 and also
removes the need to list org.eclipse.jgit.console in both profiles.
