Adding No-op functions required for NodeJS compatability

[smittals2]

Description of changes:

Added OPENSSL_init and SSL_CTX_set_dh_auto as no-op functions to support compilation with NodeJS. OPENSSL_init does nothing by design and SSL_CTX_set_dh_auto because DH is not supported with SSL in AWS-LC.
