The only user of PCBC mode (Propagating Cipher Block Chaining mode) was
net/rxrpc/rxkad.c, which now uses local code instead.

While PCBC was an interesting cryptographic experiment, it has largely
been relegated to the history books and academic exercises.  It is
non-parallelizable (i.e., very slow) and doesn't actually achieve the
integrity properties it was apparently intended to achieve.

Remove support for it from the crypto API.
