Revert "systemd-systemctl: Create machine-id with "uninitialized" text in it"

This reverts commit 33d9b3a8ed186c2d212acb83f715367912010e7f.

The reverted patch was forcing systemd to do preset-all at boot time (first boot)
in a function that simuilates 'preset-all' at rootfs time. This is not right.

To force a first boot, just do not run this function, as said in the comment:
"""
    # If we populate the systemd links we also create /etc/machine-id, which
    # allows systemd to boot with the filesystem read-only before generating
    # a real value and then committing it back.
    #
    # For the stateless configuration, where /etc is generated at runtime
    # (for example on a tmpfs), this script shouldn't run at all and we
    # allow systemd to completely populate /etc.
"""

For example, removing 'systemd_preset_all;' from IMAGE_PREPROCESS_COMMAND in some
distro conf file will achieve the same effect of the original patch.
