Keep the image mounted when installing a diskless image to disk

Browse Source 
With installtodisk and confluent_imagemethod=untethered (or
uncompressed) imageboot.sh first extracts the image to RAM and tears
down the image mount and the cryptimg device. installimage then hands
the empty /mnt/remote to image2disk.py, which wipes the target disk and
fails with:

  FileNotFoundError: [Errno 2] No such file or directory: '/dev/mapper/cryptimg'

Writing the image to disk never needs the RAM copy, so treat the image
method as tethered when installtodisk is set. The same profile can then
be switched between untethered and installtodisk by only adding or
removing installtodisk.
