OpenSSL: Allow pkcs11_module_path to be NULL

Browse source 
New versions of engine_pkcs11 will automatically use the system's
p11-kit-proxy.so to make the globally-configured PKCS#11 tokens available
by default. So invoking the engine without an explicit module path is
not an error.

Older engines will fail but gracefully enough, so although it's still an
error in that case there's no need for us to catch it for ourselves.
