Add MEGAsync.app latest

[jeroenseegers]

This is a follow-up to #5338. I had no issues installing and running
the MEGAsync client using this caskfile.

Also, it seems that #5338 turned into a VMWare Fusion caskfile somewhere along the way.

You had no issues because you’re likely linking apps to /Applications (with --appdir), which is part of the issue (since it’s not the default).

It doesn’t look like they’ll actually do anything about it anytime soon, though, and we since had similar cases that were solved, so please add to the cask (below app, with one empty line above it and none below):

caveats do
  <<-EOS.undent
    #{token} only works if called from /Applications, so you may need to install it with
      brew cask --appdir=/Applications install #{token}

    Alternatively, you can create an extra link in /Applications, after installing
      ln -s '#{staged_path}/MEGAsync.app' '/Applications/MEGAsync.app'
  EOS
end
