XD-2326 - Fixed Windows file path issues

spring-xd-hadoop will not run on windows. Those are skipped if running

* A few tests are disabled for windows.  Others work by applying
FixtureUtils.preventShellEscapeProcessing() to file paths.

* reverted DatasetOutboundChannelAdapterIntegrationTests.xml
