Eric Biggers f17f9e9069 crypto: testmgr - test in-place en/decryption with two sglists ...

As was established in the thread
https://lore.kernel.org/linux-crypto/20220223080400.139367-1-gilad@benyossef.com/T/#u,
many crypto API users doing in-place en/decryption don't use the same
scatterlist pointers for the source and destination, but rather use
separate scatterlists that point to the same memory.  This case isn't
tested by the self-tests, resulting in bugs.

This is the natural usage of the crypto API in some cases, so requiring
API users to avoid this usage is not reasonable.

Therefore, update the self-tests to start testing this case.
