These are already listed in the respective deploy-* elements, and
if we include them here then they get added to every ramdisk built
with dracut. That causes issues for elements that don't need
something like tgtd because it won't be installed and the
binary deps script will fail.

We don't actually need a real value for the root kernel param, and
requiring one causes problems for things like the discovery ramdisk
that don't pass in a disk= parameter. Dracut seems to be happy to
take /dev/zero as the value, so we can just always use that.

A similar change was needed in the normal ramdisk element as part
of ae928057bd to avoid running
cleanup immediately after the ramdisk build completes.

Instead of hard-coding a list of binaries to include in the dracut
ramdisk, use the existing binary-deps.d functionality to provide a
list. This will allow other ramdisks (such as discovery) to add
the binaries they need.

The element builds dracut from source on Ubuntu because the
Ubuntu dracut package is broken and very old, so it can't be
installed properly and causes a number of other issues that
are fixed by using a newer version of Dracut.
This initial version should work in virtualized environments.
Further validation of its suitability for real baremetal
deployments will need to be done in the future, but this should
be sufficient to enable that work.
Regarding Dracut specifically, in order to limit the changes
needed in the existing scripts this element continues to use a
cut down version of the /init script that we were building for the
existing ramdisk. However, instead of running it as pid 0 it is
run as a Dracut pre-mount hook. This allows Dracut to set up all
of the hardware and system bits, while falling early enough in the
Dracut sequence to complete the deployment before Dracut would try
to boot off the hard disk.
