runqemu: explicitly set image format 

QEMU produces a warning if drive format is not specified:
  WARNING: Image format was not specified for
  'tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.wic'
   and probing guessed raw.
   Automatically detecting the format is dangerous for raw images,
   write operations on block 0 will be restricted.
   Specify the 'raw' format explicitly to remove the restrictions.

Set image format to 'vmdk', 'qcow2' or 'vdi' for correspondent image
types. Set it to 'raw' for the rest of image types.
