So that programs which interface with systemd can detect whether or not
systemd is present, and fall back to alternate code paths when it's not.

As I understand matters (without having actually dug into the code),
that detection code literally is what libsystemd0 *is*; when systemd is
present, it passes through function calls to be handled in appropriate
places, and when systemd is not present, it returns an appropriate
default or failure value.
