Bug#913061: systemd: stop shipping /bin/systemd

[Ansgar Burchardt]

Package: systemd
Version: 239-11
Severity: minor
File: /bin/systemd

Running `systemd` in an interactive shell is not a good idea.  To
avoid this happening by accident, the /bin/systemd ->
/lib/systemd/systemd symlink should no longer be shipped.

Documentation such as [1] still suggests to use `init=/bin/systemd`
which would result in non-bootable systems.  (The initramfs might be
able to catch this and run /lib/systemd/systemd instead in most cases
as unbootable systems are not nice.)
