build: define HAVE_OPENSSL macro for cctest

cctest build target wasn't defining the HAVE_OPENSSL macro when
node_use_openssl was true, causing inconsistencies on most
`node::Environment` member's addresses. For example, if someone
wanted to access the context of an environment by using
`node::Environment::context()`, the object returned by the
function was pointing to an invalid address.
