Remove matrix from java compat suites (#132)

Platform does not test compat tests with other jvms. We should not do it
as well. It'll consume a lot of resources because ubicloud is not
planned for client-compatibility-suites repo.

There're 96 jobs that some of which takes 4 hours to run, it's not
feasible to run that many combinations
