This update for systemd fixes the following issues:

- Name libsystemd-{shared,core} based on the major version of systemd and
  the package release number (bsc#1228081, bsc#1256427)
  This way, both the old and new versions of the shared libraries will be
  present during the update. This should prevent issues during package updates
  when incompatible changes are introduced in the new versions of the shared libraries.
- detect-virt: bare-metal GCE only for x86 and i386 (bsc#1254293)
- timer: rebase last_trigger timestamp if needed
- timer: rebase the next elapse timestamp only if timer didn't already run
- timer: don't run service immediately after restart of a timer (bsc#1254563)
- test: check the next elapse timer timestamp after deserialization
- test: restarting elapsed timer shouldn't trigger the corresponding service
- Reintroduce systemd-network as a transitional dummy package containing no files (bsc#1254202)
  The contents of this package were split into two independent packages:
  systemd-networkd and systemd-resolved. However, the initial replacement caused
  both network services to be disabled. Consequently, the original package has
  been restored as an empty transitional package to prevent the disabling of the services.
  It can be safely removed once the update is complete.
- units: don't force the loading of the loop and dm_mod modules in systemd-repart.service (bsc#1248356)
- units: add dep on systemd-logind.service by user@.service
- detect-virt: add bare-metal support for GCE (bsc#1244449)
