Can not start on Debian 8/9 if dbus package is not presented.

Tarantool can not start on Debian 8/9 if package dbus is not presented.
In logs there is only the notorious

got signal 15 - Terminated

Issue is in a way tarantool determines if it runs under systemd:
It is done by parsing output of systemctl, run by trantool user , but it can't start under non-root.

# sudo -u tarantool systemctl
Failed to get D-Bus connection: No such file or directory

Issue is in absence of dbus socket - it is not presented if dbus service is not presented:

systemctl status --all dbus.socket

But if dbus package is installed - all start to work as a charm instantly.

Probably other way of determining if trantool run under systemd is required.

Confirmed

Probably we should add an option to tarantoolctl to avoid daemonization, e.g. tarantoolctl start example --foreground. Actually I plan to remove /usr/bin/tarantoolctl wrapper for systemd case, but it is complicated task.

I realized that --foreground will break tarantoolctl start INSTANCE -> systemctl start tarantool@INSTANCE redirect. Any better ideas how to detect systemd? Nothing from 1 is portable between all distros...
