rootfs: Don't remove files from the rootfs by default

Browse Source 
Recent PR #10732 moved the deletion of systemd files and units that were
deemed uneccessary by 02b3b3b977 from `image_builder.sh` to `rootfs.sh`.
This unfortunately broke `rootfs.sh centos` and `rootfs.sh -r` as used by
some other downstream users like fedora and RHEL, with the following error :

  Warning  FailedCreatePodSandBox  1s (x5 over 63s)  kubelet
   Failed to create pod sandbox: rpc error: code = Unknown
     desc = CreateContainer failed: Establishing a D-Bus connection

Caused by:
    0: I/O error: Connection reset by peer (os error 104)
    1: Connection reset by peer (os error 104)

This is because the aforementioned distros use dbus-broker [1] that requires
systemd-journald to be present.

It is questionable that systemd units or files should be deemed unnecessary
for _all_ distros but this has been around since 2019. There's now also a
long-standing expectation from CI that `make rootfs && make image` does
remove these files.

In order to accomodate all the expectations, add a `-d` flag to `rootfs.sh`
to delete the systemd files and have `make rootfs` to use it.
