Use junit-host instead of junit

Use framework/junit-host.jar instead of framework/junit.jar

Ran the script before and after making the change and it failed
in the same way with a build error but it was not due to a
problem with JUnit.

Bug: 30188076
Test: make checkbuild and ran the test-dicttool.sh script
