openssl: Fix AES-GCM with BoringSSL 

BoringSSL only supports a limited list of (hard-coded) algorithms via
EVP_get_cipherbyname(), which does not include AES-GCM.  While BoringSSL
deprecated these functions they are also supported by OpenSSL (in BoringSSL
a completely new interface for AEADs was added, which OpenSSL currently does
not support).
