[PATCH 8/8] rootfs: stub both dracut and update-initramfs on dracut

["'Felix Moessbauer' via isar-users" <isar-users@googlegroups.com>]

The former one can be used as a wrapper even if dracut is used to
actually generate the initrd. If it is used as wrapper and dracut is
stubbed, this might fail as the wrapper expects output from dracut.

As of now, this did not result in any issues, as all dracut-native
targets (where we do explicitly enable dracut in isar) just use the
wrapper instead of calling dracut directly.
