fix: missing resource files in apache-xml.jar

include_srcs: true accidentaly excluded the resource files
(output_xml.properties, etc), but included java source files.

Switching to java_resource_dirs to correctly include the resource files.

Test: unzip -l out/target/product/walleye/system/framework/apache-xml.jar
shows the *.properties files.
