RFR(M) : 8211171 : move JarUtils to top-level testlibrary

[Igor Ignatyev]

here is the webrevs w/ JarUtils from default package inserted into jdk.test.lib.util.JarUtils:
whole patch: http://cr.openjdk.java.net/~iignatyev//8211171/webrev.01/index.html <http://cr.openjdk.java.net/~iignatyev//8211171/webrev.01/index.html>
> 655 lines changed: 239 ins; 355 del; 61 mod;
incremental: http://cr.openjdk.java.net/~iignatyev//8211171/webrev.0-1/index.html <http://cr.openjdk.java.net/~iignatyev//8211171/webrev.0-1/index.html>
> 476 lines changed: 239 ins; 203 del; 34 mod;

doing that, I noticed that both updateJarFile and createJarFile don't close Stream<Path> from Files::find, the current patch fixes that.

I'd prefer to "merge" all three instances together, where merge might be implemented as conversion of tests.

It makes me wonder if it would be better to just convert tests rather than merging. A few convenience methods added to the JarUtils you are moving would make that easier.
