Fix EVP_CIPHER_CTX_copy for AES-GCM.

7578f3f0dea091a3392f0be3216989bdc7355ad2 made it work, but
26ba48a6fbbf7b25bbfb521d3f5591e2d5a0b4bd regressed it by losing the
EVP_CIPH_CUSTOM_COPY flag. Additionally, we've since added an alignment
requirement to EVP_AES_GCM_CTX, which complicates things.

Thanks to Guido Vranken for catching this!
