In jar-tool, use apache commons FileUtils.moveFile to use copy when target of jar write is across filesystem boundary

This change updates File.rename() to use the apache commons FileUtils.moveFile() when writing out a jar file in JarBuilder.write().  This change uses a simple file rename when possible, or a copy if the two files can't be renamed (if the destination is on a different filesystem, for example.)

Testing Done:
Ran ./pants goal test tests/java/com/twitter/common/jar/tool

It would be great if Patrick could test out in their environment where this is a problem:

1.) in twitter/commons use `./pants goal binary --binary-deployjar src/java/com/twitter/common/jar/tool/:main` to produce a self-contained tool jar at dist/jar-tool.jar
2.) in pantsbuild/pants edit like so adapted for your local paths:
$ git diff
diff --git a/BUILD.tools b/BUILD.tools
