Reland: Add jni_libs property to java tests

Add jni_libs property to java tests and treat it as test data that
should be copied to the lib or lib64 directory in the test directory.

This relands I3a118b933ab30dcd731c6dc2708da9bc63ab5520 with fixes for
the test on mac.

Fixes: 176593487
Test: java_test.go
