When using docker-machine on a Mac only the /Users folder is shared with the VM. Uploads fail since the normal tmpdir is not shared. This change uses the local packer directory (usually when run in the users home folders) allowing it to work without setting TMPDIR explicitly. A better fix would be to use the docker API directly but that would force users to use docker API version 20+. - fixes #901, fixes #1752, fixes #2436, fixes #2675, fixes #2697.
