vagrant post-processor does not export additional disks from qemu

[rgl]

Overview of the Issue

#7791/#6139 introduced the disk_additional_size property to add additional disks to a qemu vm and that works nicely, but the vagrant post-processor is not exporting the additional disks:

$ tar tvf esxi-7.0-amd64-libvirt.box
