Re-org the merge_zips logiic under Turbine rule.

Mac java build has flaky error for merge_zips. The error happend is
because both turbine.jar.premerged and static_java_libs are missing.

We allow one of them can be missing, but we don't allow both of them are
missing. So re-org the merge_zips logic to see if the input of Turbine is
empty or it is due to Turbine internal.
