[CRYPTO] tcrypt: Change the usage of the test vectors
The test routines (test_{cipher,hash,aead}) are makeing a copy of the test template and are processing the encryption process in place. This patch changes the creation of the copy so it will work even if the source address of the input data isn't an array inside of the template but a pointer.
