When an algorithm of the new "lskcipher" type is exposed through the
"skcipher" API, calls to crypto_skcipher_setkey() don't pass on the
CRYPTO_TFM_REQ_FORBID_WEAK_KEYS flag to the lskcipher. This causes
self-test failures for ecb(des), as weak keys are not rejected anymore.
Fix this.

As an aid to the transition from cipher algorithm implementations
to lskcipher, add a temporary wrapper when creating simple lskcipher
templates by using ecb(X) instead of X if an lskcipher implementation
of X cannot be found.
This can be reverted once all cipher implementations have switched
over to lskcipher.

Add a new API type lskcipher designed for taking straight kernel
pointers instead of SG lists. Its relationship to skcipher will
be analogous to that between shash and ahash.
