[tor-qa] Please test bundles with slightly rearchitected meek-http-helper

[David Fifield]

Dear tor-qa, please test the meek transport in these test bundles:
	https://people.torproject.org/~dcf/pt-bundle/4.5a4-12716-1/
You only need to test that meek bootstraps and that there are no
processes left running when you close the browser. Here is the test
procedure:
	1. Click "Configure".
	2. Choose "Yes" on the bridge/pluggable transport question.
	3. Choose meek-amazon, meek-azure, or meek-google (doesn't
	   matter which) from the list.
	4. Choose "No" on the proxy question.
	5. Make sure it bootstraps 100%.
	6. Close the browser and check the process list; make sure there
	   are no processes with "meek" in the name.

I tested on linux64 but not any of the other platforms.

The purpose of these bundles is https://trac.torproject.org/projects/tor/ticket/12716,
which changes the way the browser helper is spawned so that it can be
used outside of Tor Browser.
