Support for cryptoloop has been officially marked broken and deprecated
in favor of dm-crypt (which supports the same broken algorithms if
needed) in Linux 2.6.4 (released in March 2004), and support for it has
been entirely removed from losetup in util-linux 2.23 (released in April
2013).  Add a warning and a deprecation schedule.

Would probably look better to queue with the 5.15 patches at this point.
Which then begs the question of whether we want to make the removal
target 5.17 instead.

File locking also just managed to sneak in a short-term deprecation for
a very similar situation.
