core-image-minimal-initramfs: split out core-image-minimal-install-initramfs

core-image-minimal-initramfs wasn't buildable on all archs, due to its
installation scripts and dependence upon grub/parted/etc. Split out the
install bits into a separate image, and alter the default image for image-live
to use the newly split out install image. This keeps the main image as generic
as its image name implies, and makes it buildable on non-x86 archs.

This should address hf2013.11-001-initramfs in a cleaner way.
