renamed linktest executable

This would resolve issue #1041.... I just don't know if this would break anything. I assume it won't but still.. -- hence the PR and no direct push. 😶‍🌫️

I don't see why this would be a problem, but @Zalastax will be more familiar with it

BTW I think best we do PRs for everything anyway, even when you merge yourself, not least because it makes release notes easier.

Ok, got it :)

While we're at it: Do we need to host the Ableton Link code ourselves here or could we reference the ableton repo as a submodule (with a specific commit)? Maybe @Zalastax can answer this too.

The renaming should be fine.

I used submodules originally but we changed to use file copy: #891 (comment)

I don't see much benefit to change back to submodules but I think it might be time to update the files.
