Issues reproducible with ubuntu-20.04.4-live-server-amd64.iso.

Apparently, ctrl-c does not stop the integrity check anymore
because casper-md5check runs as systemd service/disconnected
from plymouth. Per [1], iiuic. -- Well, this is _not_ a bug.

So, fsck.mode=skip is the only option available.

However, there's a bug in casper-md5check that ignores that
_if_ it is the last option in /proc/cmdline (likely, if the
user adds it after '---' or deletes '---' to insert it.)

Workaround: make sure to add fsck.mode=skip before '---'.

Patch proposed [2], with technical details and testing.
