linux-qcom-bootimg.inc: support bundling initramfs into bootimages

Add support for bundling initramfs into android boot images. For example
this allows one to build bootable images containing the kernel and all
built modules/firmware to test them without flasing actual images to the
device.

To create kernel+initramfs bundles, just define INITRAMFS_IMAGE.
