This update for systemd fixes the following issues:

Security issue fixed:

- CVE-2017-18078: tmpfiles: refuse to chown()/chmod() files which are
hardlinked, unless protected_hardlinks sysctl is on. This could be used
by local attackers to gain privileges (bsc#1077925)

Non Security issues fixed:

- core: use id unit when retrieving unit file state (#8038) (bsc#1075801)
- cryptsetup-generator: run cryptsetup service before swap unit (#5480)
- udev-rules: all values can contain escaped double quotes now (#6890)
- strv: fix buffer size calculation in strv_join_quoted()
- tmpfiles: change ownership of symlinks too
- stdio-bridge: Correctly propagate error
- stdio-bridge: remove dead code
- remove bus-proxyd (bsc#1057974)
- core/timer: Prevent timer looping when unit cannot start (bsc#1068588)

- Make systemd-timesyncd use the openSUSE NTP servers by default
Previously systemd-timesyncd used the Google Public NTP servers
time{1..4}.google.com

- Don't ship /usr/lib/systemd/system/tmp.mnt at all (bsc#1071224)
But we still ship a copy in /var.
Users who want to use tmpfs on /tmp are supposed to add a symlink in
/etc/ pointing to the copy shipped in /var.
To support the update path we automatically create the symlink if
tmp.mount in use is located in /usr.

- Enable systemd-networkd on Leap distros only (bsc#1071311)
