crypto: pcbc - remove ability to wrap internal ciphers
Following commit 944585a64f5e ("crypto: x86/aes-ni - remove special handling of AES in PCBC mode"), it's no longer needed for the PCBC template to support wrapping a cipher that has the CRYPTO_ALG_INTERNAL flag set. Thus, remove this now-unused functionality to make PCBC consistent with the other single block cipher templates.
