Add openssl 3.0.0 support about libcaes

[joachimmetz]

Looks like EVP_CIPHER_CTX_set_padding should be used after EVP_CipherInit_ex

This is mentioned in https://www.openssl.org/docs/man1.1.1/man3/EVP_CIPHER_CTX_set_padding.html

EVP_CipherInit_ex returns unable to initialize cipher with error: error:03000083:digital envelope routines::no cipher set due to missing cipher in error tests. Changed tests to make sure key is set before error tests are run.

Issue looks to no longer happen with openssl 3.0.1
