fix(getinstdisk): serve every installer from one script
The RHEL 10 support added a second copy of the script. The copy carries the Xen fallback and a failure log that the common script does not, and the common script carries the Intel RSTe/VROC fallback that the copy does not. A RHEL 10 node whose OS disk is a VROC volume therefore fell back to /dev/sda, and every later fix to disk selection had to be written twice to reach both. Fold the Xen fallback and the failure log into the common script and delete the copy. The RHEL 10 installer includes the common script, as the other installers already do. The failure log runs only when the including script defines msgutil_r, because the subiquity path does not.
