apiv2 tests: finally fix POST as originally intended

When I originally wrote this code I had no idea what POST
would look like so I did a sloppy job, deferring making it
usable. Now that we have some real-world examples in place,
I have a better understanding of what params look like and
how to make tests more readable/maintainable. (Deferring isn't
always bad: one of my early ideas was to separate params using
commas; that would've been a disaster because some JSON values,
such as arrays, include commas).

This commit implements a better way of dealing with POST:

  * The main concept is still 'key=value'
    * When value is a JSON object (dictionary, array), it
      can be quoted.
    * Multiple params are simply separated by spaces.
      The 3-digit HTTP code is a prominent, readable separator
      between POST params and expected results. The parsing
      code is a little uglier, but test developers need
      never see that. The important thing is that writing
      tests is now easier.
  * POST params can be empty (this removes the need for a
    useless '')

I snuck in one unrelated change: one of the newly-added
tests, .NetworkSettings, was failing when run rootless
(which is how I test on my setup). I made it conditional.
