tls: fix OpenSSL engine in child processes

tls_init.c calls OPENSSL_init_ssl(); this initializes the
global engine linked-list and this cannot be reset in the child.

To avoid linked-list corruption we manually instantiate
the engine object required for loading private keys instead of
relying on CONF_modules_load_file().
