demos: wire up tls-server-block

The blocking TLS server demo code was added f4b4a185b546 "MVP demo TLS
server", which, while was applied after 2000281dad31 "Convert demos
to primary build system", was authored before, and hasn't been updated
accordingly.  Rescind that omission by add the relevant introes
to build.info.

Also, while at it, mention tls-server-block in demos/README.txt.
