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.
