Fix install script to specifically require xorriso

The dependency check was accepting any ISO tool (mkisofs, genisoimage,
or xorriso), but the install commands now specifically install xorriso.

Updated checks to require xorriso specifically since:
- It handles both ISO9660 and UDF formats
- Required for RIP module to extract UDF DVD ISOs
- Now installed by all package managers in the script

This ensures the install script will detect and install xorriso even
if older tools like genisoimage are already present.
