75b34baa98 dracut-ramdisk: fix support for elements with ramdisk-install.d
Copy all of TMP_MOUNT_PATH into the ramdisk so that
ramdisk-install.d actions are respected.

Includes a workaround for a bug in Dracut that caused the copy
to fail.

Also moves init instead of copying it so we don't conflict with
the Dracut init.

8ee66ec8ec Remove duplicate binary-deps from dracut-ramdisk
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.

f528aa316e Simplify Dracut cmdline script
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.

0db6b9b401 Unset trap before dracut ramdisk build script exits
A similar change was needed in the normal ramdisk element as part
of ae928057bd to avoid running
cleanup immediately after the ramdisk build completes.

bb8126e887 Use binary-deps.d for dracut ramdisks
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.

eed30adc48 Enable dracut deploy ramdisks
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.
