The dd step is the longest, so showing the progress is nice. But
dd does not show how big the file is. Hard-code the size since
we know how big it is.

All trainers are now using stretch (or higher), so use the
status=progress feature. Also, increase the blocksize to
128M since that amount should be available on the cloning
host.

After calling partprobe, userspace may need a moment to delete any
previously existing device nodes. Sleep a second to give userspace
a chance to do this before checking for the nodes to appear.
Also, copy the vmdk files in parallel. Otherwise it takes forever
to setup the USB disks.

As of 6f5bc54("lx-trainer-vm: increase image size to 64GiB") the
root filesystem is now large enough for all layers and training
work. So there is no reason to create a separate /home partition.
Change the dd-multi.sh script to instead:
- create an exfat partition
- convert the image to VMDK format and copy to exfat partition
This allows participants who cannot boot from USB to be able to
use VMware or VirtualBox during the training. They need only to
create a virtual machine and set the "training-hd.vmdk" file as
the hard drive.

Rename the variable representing the extra partition. Until now
this was /home but it will be changed to be an extra partition.

Until now, a separate /home partition was created during post-build.
However, now that the entire root filesystem will also need to exist
as a VMDK file, it is simpler to just have the entire root filesystem
in a single partition.
64GiB is currently large enough for the largest training: Yocto,
20GiB in layers with worst case about 10GiB in data generated during
the training.

The generated image will be post-modified to include an exfat
partition with a VMDK version of the image stored. This can be
used by VMware or VirtualBox in case the image cannot be directly
booted. Having the exfat tools in the image allows for usage of
that partition by the booted system (if needed).
VirtualBox needs the dkms drivers in order to provide a larger
graphic screen.

The linaro toolchain creates files with some obscure user/group.
Instead of trusting the owners/permissions of the downloaded
archives, recursively set all /opt to root:root. If for some
reason any files are setuid, this will also clear that bit.

It seems that calling umount directly after mount can lead to a
busy error. With strace on umount the problem goes away. It must
be a very small window. Someone should debug the umount syscall
on this. It is reproducable with:
./dd-multi.sh lx-trainer.img /dev/sdx
(i.e. regular training image and no layers)
Implement a workaround for this for now.
From the comments...
If there were no layer files added, umount might return a busy
error since we just mounted. (Possibly a kernel bug.) By
accessing the filesytem before unmounting it, the mount/umount
problem seems to go away. Use "ls" to access the filesystem.

Tarballs are copied to the USB drives and then unpacked in a
