Review request: 8152502: tools/jdeps/modules/GenModuleInfo.java and TransitiveDeps fails on windows

[Mandy Chung]

These jdeps tests fails running on windows “Error. failed clean up files after test”.  A bug in the tests and implementation that calls Files.walk without try-with-resources.

This fix calls Files::walk with try-with-resources.  I wasn’t quite able to reproduce the error on my windows machine.  I’d like to push this fix and address any issue, if any.
