Adds XSLTNamespaceFixupTests for the previously-untested live paths in XSLTNamespaceFixup.apply: generated ns0/ns1 prefixes for namespaced attributes with no carried prefix, and xmlns="" undeclaration of an inherited default namespace on an unqualified element (XSLT 1.0 7.1). Exact serialized-output assertions, matching the existing XSLT test idiom.
