[PATCH v2] guestfs: eliminate rescue initramfs images from base images

[Jeff Layton]

dracut-config-rescue generates the "rescue" images in the /boot
partition (at least on Fedora hosts). This is a waste of space since
these are ultimately throwaway VMs.

Uninstall dracut-config-rescue from the base images, and delete any
already-generated images , thus saving space for more "make linux"
invocations.

While we're at it, lets delete any already-generated images too.
