Refactor API build endpoint to be more compliant

* Refactor/Rename channel.WriteCloser() to encapsulate the channel
* Refactor build endpoint to "live" stream buildah output channels
  over API rather then buffering output
* Refactor bindings/tunnel build because endpoint changes
  * building tar file now in bindings rather then depending on
    caller
* Cleanup initiating extra image engine
* Remove setting fields to zero values (less noise in code)
* Update tests to support remote builds

Fixes #7136
Fixes #7137

+Package channel provides helper structs/methods/funcs for working with channels
+
+Proxy from an io.Writer to a channel:
+
+	w := channel.NewWriter(make(chan []byte, 10))
+	go func() {
+		w.Write([]byte("Hello, World"))
+	}()
+
+	fmt.Println(string(<-w.Chan()))
+    w.Close()
+
+Use of the constructor is required to initialize the channel.
+Provide a channel of sufficient size to handle messages from writer(s).
