Do not build Unite-Qt .dmg for Mac OS in Gitian

[cmihai]

This commit removes the .dmg package (which packages Unite-Qt for Mac OS) from Gitian and updates the tests accordingly.

As discussed in #28, we will be shipping a .tar.gz with united, but without unite-qt for Mac from now on.

Actually, what is the problem with a DMG? After all that's just some fancy archive.

[cmihai]

It packaged the Unite-Qt binary, and only that. Since we're getting rid of Qt, it was easier to get rid of the DMG as well, rather than untangle all the assumptions and dependencies on Qt and package the united in it.

On the user side, people are used to "install" applications on Mac by dragging them from the DMG image to the dock or application folder or whatever, then clicking on the icon to launch it. Since united and unite-cli are console applications, this approach doesn't really work here (but it might work for the Electron wallet, so I'll look into packaging it into a .dmg once it's all done and tested).

I see, makes sense.

I'm wondering whether it would make sense to explore the option of having a future bundle for macos which would just start unit-e, hanging around in the systray area, like dropbox or google drive, or docker do, with "start/stop" menu and maybe a third item which opens a sort of terminal which you can use to give commands to the node. Would surely be a nice thing to have :-) I think I would even use it!

As I've said elsewhere. A proper DMG with a drag-and-dropable app can be given with the electron wallet. Would it come bundled with a united by the way? And would it also be built using gitian?

Concept ACK – The less code in the build system, the less to be built when moving to CMake 🎉 – #61

Particl-desktop downloads their daemon on first launch, but there's nothing preventing us from shipping our own with the installer. And we want reproducible builds, so yes to Gitian (there's issue dtr-org/unit-e-desktop#51 for this).

Build the mac archive. I've had to disable the Qt man, but that's to be fixed in another PR.
