units: make system-update-pre.target a passive unit (#9349)

This is an additional synchronization point normally not needed. Hence,
let's make it passive, i.e. pull it in from the unit which wants to be
ordered before the update service rather than by the update service
itself.

 CHANGES WITH 239 in spe:
 
         * NETWORK INTERFACE DEVICE NAMING CHANGES: elogind-udevd's "net_id"
-          builtin may name network interfaces differently than in previous
-          versions. SR-IOV virtual functions and NPAR partitions with PCI
-          function numbers of 8 and above will be named more predictably, and
-          udev may generate names based on the PCI slot number in some cases
-          where it previously did not.
+          builtin will name network interfaces differently than in previous
+          versions for virtual network interfaces created with SR-IOV and NPAR
+          and for devices where the PCI network controller device does not have
+          a slot number associated.
+
+          SR-IOV virtual devices are now named based on the name of the parent
+          interface, with a suffix of "v<N>", where <N> is the virtual device
+          number. Previously those virtual devices were named as if completely
+          independent.
+
+          The ninth and later NPAR virtual devices will be named following the
+          scheme used for the first eight NPAR partitions. Previously those
+          devices were not renamed and the kernel default (eth<n>) was used.
+
+          "net_id" will also generate names for PCI devices where the PCI
+          network controller device does not have an associated slot number
+          itself, but one of its parents does. Previously those devices were
+          not renamed and the kernel default (eth<n>) was used.

+        * A new unit "system-update-pre.target" is added, which defines an
