(PA-6507)(PA-6736) Gem install rexml to 3.3.2 for CVE-2024-35176 and CVE-2024-39908 in 7.x

 - The CVEs were fixed from rexml version 3.2.7 (CVE-2024-35176) and 3.3.2 (CVE-2024-39908).
 - Patching for the CVE wasn't getting applied cleanly and had a lot of conflicts. So updated the gem version to 3.3.2 in the rexml component file.
 - This addresses the CVEs for 7.x.
 - For solaris-10-sparc and solaris-11-sparc, we ignore dependency when installing rexml since the ruby in these platforms tries to install strscan (rexml's dependency) but fails while building native extensions. We can ignore installing strscan since it is shipped with ruby 2.7.8 as its default gem.
