Remove the AF_UNIX client/server communication protocol.

It has been superseded by gRPC.

RELNOTES[INC]: Blaze doesn't support Unix domain sockets for communication between its client and server anymore. Therefore, the --command_port command line argument doesn't accept -1 as a valid value anymore.
