When compiling with Lagom, we give both LibWebSocket and the WebSocket
IPC service the Lagom:: prefix as an alias, but strip the Lib from all
library target names before applying the prefix. This creates a conflict
when external projects used the aliased name between the server and the
library. Give WebSocket a name that deconflicts it, but keep the binary
name the same, /bin/WebSocket.
The WebSocket service isolates communication with a WebSocket to its
own isolated process. Similar to other isolating services, it has its
own user and group.
