Only run lint_tests on java_library not java_export

Running list_tests on java_export will run afoul by trying to run
spotbugs on included dependency that will clearly fail like
`java_proto_library`.

Instead, the lint tests should only operate on the sources that comprise
the `java_library` the export target eventually creates.
