refactor(tvix/castore): use DuplexStream instead of unix socket r/6728

We can use DuplexStream to create to bidirectional pairs, which avoids
manually waiting for unix sockets to pop up and connect, and creating
temporary directoires to create the unix sockets in.

Turns out, we also don't actually need to spawn the server in a separate
runtime, it works just fine these days. This might be due to all the
sync barriers in between being gone.
