nginx, add no_lua pseudoflavour, use it by default for now to unbreak

[Stuart Henderson]

The build problem with nginx following libressl changes is only
in the lua module ..

/usr/obj/ports/nginx-1.10.2/nginx-1.10.2/lua-nginx-module/src/ngx_http_lua_ssl_ocsp.c:493:
 error: 'SSL' has no member named 'tlsext_status_expected'

OK to add bits to the Makefile so we can disable the lua build,
and use that by default for now to unbreak build?
