image-vmdk: Create image_vmdk class and setup image and image_types to use it

This creates a new image_vmdk class similar to live. The image_vmdk
class needs to have a hddimg created by the image-live class, so it
inherits it directly.

The changes to image_types is to ensure that both live and vmdk images
get the ext3 tools and dependencies.
