One exec of one binary for a deployment

deploy-for.nix built three wrappers, each execing the tool with a
different subcommand and its flags, because a deployment needed apply and
the two things a stopped deployment needs. It builds one now: nix writes
a file saying which router this is and where the halves are, and the
wrapper is one exec of one binary with one flag.

  nix run .#deploy-ccr2004                 applies
  nix run .#deploy-ccr2004 -- download     reads the router into the record
  nix run .#deploy-ccr2004 -- import-rest  finishes a stopped deployment

Which router is being talked to moved from in front of every subcommand
into the ones that need it, since router is told by its file and the rest
are told on the command line.

--download-with and --finish-with are gone with the wrappers they named:
the messages take argv[0] and add the subcommand, so they name whatever
the reader actually typed.

Two other duplications while looking: run_command_remotely was
capture_command_remotely with the answer thrown away and its own copy of
the channel handling, including the last unwrap on a read in that file;
and download_export was fetch_export with a write on the end.

The vm test's environment is runtimeEnv for everything known when it is
built, which is all of it but the disk it makes and the two a caller
passes in.
