Skip java-api-generator tests when running on windows-type OS
Xtend code generation uses the "line.separator" system property to
generate proper line endings, and there is no possibility to override
this setting w/o modifying the system property. This change disables
some tests to avoid misleading failures when running those on the
windows type os.
