We use a read-only rootfs (i.e., we have read-only-rootfs set in
IMAGE_FEATURES). However, we mount /etc from a separate writable flash
partition. But because of how some packages are considered unneeded
and subsequently removed from the rootfs if it is read-only, we cannot
enable, e.g., shadow in our image. The list of unneeded packages is
hardcoded in lib/oe/rootfs.py, making it near impossible to override
this.

With this change the list of unneeded packages is moved to a variable
(ROOTFS_RO_UNNEEDED) in image.bbclass, which makes it easy to adopt it
as needed.

There was code in lib/oe/rootfs.py which was meant to not add
update-rc.d to the list of unneeded packages if both systemd and
sysvinit are enabled in DISTRO_FEATURES. I have removed this code
since a) it is no longer needed (as it only made sense when the
unneeded packages were removed based on whether package-management was
enabled or not), and b) it can never have worked as intended (because
the explicit addition of update-rc.d to the list of unneeded packages
was not removed when the conditional addition was introduced...)
