Add support to build an ext4 image from a filesystem

This is suitable for passing to Qemu with -hda which makes it appear
as a disk to a Qemu instance. Once it appears, one can chroot into it.

Note:
- Device need not be connected, this option is only used to prepare
  a standalone image.
- BCC isn't built but is just cloned into the image.
- Other options such as --buildtar are ignored.
