kde-plasma/plasma-workspace: Improve old script detection/migration

- Drop mkdir and chmod commands
- Add missing || die
- No need for subshells to detect constant paths
- Use md5sum to detect if existing scripts were modified at all
- Clean up pre-5.17.4 scripts, they were owned by plasma-workspace anyway
