Universal USB Installer tries to remove the live-media=removable protection

If #7411 (closed) was not mistakenly protecting against this bug, UUI 1.9.5.3 would be replacing live-media=removable with root=LABEL=UUI live-media-path=/live. As a result, live-boot in the initramfs would gladly use a possibly malicious SquashFS found on the internal hard-drive.
