New version of sfdisk have different syntax for other units (suffixes
beside the numbers, instead of global --unit). The only common unit is
sector, so use that.

Theoretically it shouldn't be a problem, because module isn't installed
in initramfs by default (in dom0), but since such error would be fatal
to dom0 (will prevent it from booting), add a safety check for it.
Probably it will be required when (if) we migrate dom0 to Debian
This package is responsible for kernel modules and initramfs additions
needed in Qubes VM. When installed, it is possible to switch the VM to
use PV Grub and load the kernel from inside of VM. This greatly ease
installing custom kernel modules.
Changes:
- make qubes_cow_setup.sh working with both dracut and initramfs-tools
- add initramfs-tools configuration/scripts (including
qubes_cow_setup.sh)
- modify DESTDIR to handle multiple binary packages out of single
source

When udev is installed (and scheduled to be started), but not running
yet, plain dmsetup will deadlock on waiting for udev. Since we call
`dmsetup mknodes dmroot` anyway

This makes is possible to modify /lib/modules content - especially
install other kernel packages, without unmounting the whole
/lib/modules. Since dom0-provided modules will no longer conflict with
VM kernel packages (assuming kernel versions are different), there is no
need for qubes-kernel-vm-placeholder anymore.
Having only one subdirectory of /lib/modules mounted is somehow tricky,
because:
1. Directory name isn't always the same - it depends on kernel version.
This means that mountpoint must be created dynamically (so $NEWROOT must
be mounted in R/W for a moment).
2. There is one-command way to mount only a subdirectory of some
filesystem. So use a trick: mount it in some temporary directory, get
interesting subdir with `mount --bind`, then unmount temporary
directory.

When PV Grub will be used, VM initramfs should not contain /lib/modules
mounting code, as the VM root.img will already contains kernel modules.
Make it possible by splitting the module.

This is preparation for pvgrub support, where all VM kernel files will
be installed inside of VM instead of dom0.
But also the same could be used to prepare VM kernel image from any dom0
kernel.
