ruby: correct fix for CVE-2024-43398
The previous fix for CVE-2024-43398 did not include patches to provide context for the changes it made. This caused an exception at run-time when ruby parsed rexml/parsers/baseparser.rb. This was first observed when using ruby-native to build the sdformat recipe. With these additional backports, the sdformat build proceeds successfully. The REXML library was also tested manually on-target with a script that used REXML::Document.new file to parse an XML file.
