Need to pre-depend on stuff used by systemctl, so systemctl works in other package's preinst

Bug Description

systemd used to pre-depend on the libraries used by systemctl or something, but now systemctl uses libsystemd-shared, and there are no pre-depends for that, meaning that systemctl fails in maintainer scripts of other packages.

[Test case]
Grab the apt-clone file from comment #20 in bug 1766890, and upgrade it to bionic with apt dist-upgrade -o APT::Immediate-Configure=0. Make sure to not see error about missing libraries in systemctl.

[Regression potential]
Installation ordering changes. Might make things harder for apt to solve.

[Other info]
Debian 897986

Hello Julian, or anyone else affected,

Accepted systemd into bionic-proposed. The package will build now and be available at in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at . Thank you in advance!

Ran the dist-upgrade:

with bionic, bionic-updates:

Unpacking bluez (5.48-0ubuntu3) over (5.37-0ubuntu5.1) ...
systemctl: error while loading shared libraries: cannot open shared object file: No such file or directory

with bionic, bionic-updates, bionic-proposed (pinned to only allow src:systemd packages) it works fine. Well, it hangs in my container, but that might be a container thingy.
