Without reproducible images, a rebuild of the initrd will create a
different image file (due to things like creation time of the files in
the cpio archive) even if the actual contents in it are exactly the
same, adding an unnecessary download during updates.
Adding 'reproducible=yes' avoids this and creates the same image files
for the same content.
Previously, we were preparing the root very late in the boot process;
right before we switch root. The issue with that is that most services
in the initrd that run `After=initrd-root-fs.target` expect that
`/sysroot` already points to the rootfs we'll be pivoting to. Running
this late violates that assumption.
This patch fixes this by making `ostree-prepare-root.service` instead
run right after `sysroot.mount` (the physical sysroot mounted by
systemd) but still before `initrd-root-fs.target` (which is the target
signalling that `/sysroot` is now valid and ready).
This should make it easier to integrate OSTree with other initrd
services such as Ignition.

SPDX License List is a list of (common) open source
licenses that can be referred to by a “short identifier”.
It has several advantages compared to the common "license header texts"
usually found in source files.
Some of the advantages:
* It is precise; there is no ambiguity due to variations in license header
text
* It is language neutral
* It is easy to machine process
* It is concise
* It is simple and can be used without much cost in interpreted
environments like java Script, etc.
* An SPDX license identifier is immutable.
* It provides simple guidance for developers who want to make sure the
license for their code is respected

Why not to use libexecdir?
Because this directory does not exist on some distros or paths
between distros varies. There are several reasons why a well
known path is prefered, for example when generating a kernel
command line:
init=${ostree}/usr/lib/ostree-boot/ostree-prepare-root
In addition this saves us some typing in a console when wanting
to access the "ostree" cmd line.
