UnsupportedOperationException on Windows

[vsfalexanderpilch]

The build of version 1.2.1 is failing with the following error:

checkCopyScript(io.fabric8.runsh.RunShLoaderTest) Time elapsed: 0.219 sec <<< ERROR!
java.lang.UnsupportedOperationException: null
at sun.nio.fs.WindowsFileSystemProvider.readAttributes(WindowsFileSystemProvider.java:192)

PosixFileAttributes aren't supported on windows. https://stackoverflow.com/questions/23151837/get-file-owner-metadata-information-with-java/42815355 is listing some alternatives.

I found this by accident, as the docker-maven-plugin didn't create the docker-extra folder with the script.
