If you have an EFI host but the image doesn't have the EFI modules
installed the grub-install command will fail in case the --target
argument is not set. The problem is that the grub-install script will
check whether the /sys/firmware/efi file exists or not to determine if
it's an EFI installation, but this value comes from the host, so this
patch will look for the /sys/firmware/efi file and will also check if
the EFI modules are installed in the image, if not set the --target to
a non-efi platform.

The images produced by the diskimage-builder have their filesystem with
a label of "cloudimg-rootfs", so we need to change the default /etc/fstab
on fedora to reflect that.

Qemu-nbd does not perform well with older versions of qemu due to
the lack of writeback caching mode. It also only builds qcow2 images
and there is a desire for raw image support. Finally, qemu-nbd makes
it very difficult to build images concurrently due to the somewhat
opaque nature of how it selects a /dev/nbd# device. losetup, on
the other hand, makes this process very straight forward.
