Currently the write error message emitted by process-compose process logs --tail is indistinguishable from actual log output coming from the process.

processes:
  never_exit:
    command: sleep infinity
  foo:
    command: |
      echo 1
      echo 2
      echo 3

will log as:

$ process-compose process logs -u test.sock -n 2 foo 2>/dev/null
2
3
write close: write unix ->test.sock: write: broken pipe

This change will make it so that write close: write unix ->test.sock: write: broken pipe would be printed to stderr, i.e. the same command as above would log as:

$ process-compose process logs -u test.sock -n 2 foo 2>/dev/null
2
3
