crypto: remove unused include

openssl_crypto_accel.cc does not need the declarations included by
openssl/engine.h, also, openssl/engine.h was deprecated in favor of
the provider API, the engine support was removed in fedora 41.

so, let's avoid including it. please note, the "ENGINE" struct's
definition is available in openssl/types.h.
