Eric Biggers 730f67d8b8 crypto: keywrap - remove unused keywrap algorithm
The keywrap (kw) algorithm has no in-tree user.  It has never had an
in-tree user, and the patch that added it provided no justification for
its inclusion.  Even use of it via AF_ALG is impossible, as it uses a
weird calling convention where part of the ciphertext is returned via
the IV buffer, which is not returned to userspace in AF_ALG.

It's also unclear whether any new code in the kernel that does key
wrapping would actually use this algorithm.  It is controversial in the
cryptographic community due to having no clearly stated security goal,
no security proof, poor performance, and only a 64-bit auth tag.  Later
work (https://eprint.iacr.org/2006/221) suggested that the goal is
deterministic authenticated encryption.  But there are now more modern
algorithms for this, and this is not the same as key wrapping, for which
a regular AEAD such as AES-GCM usually can be (and is) used instead.

Therefore, remove this unused code.

There were several special cases for this algorithm in the self-tests,
due to its weird calling convention.  Remove those too.
