Use ProcessBuilder._merge instead of ProcessBuilder._update

The `ProcessBuilder._update` method does not properly recurse into
nested mapping like `ProcessBuilder._merge` does. Note that the
recursiveness just considers normal Python mappings and will not
recurse inside node instances that may behave like mappings, such as
`Dict` nodes.
