pam: make sure we don't assign colliding session ids if we get our session ids from multiple sources

pam: dont use $XDG_SESSION_COOKIE since CK wants that to be secret. Come up with our own $XDG_SESSION_ID based on /proc/self/sessionid if that is available

manager: get rid of destinction between running_as=system and running_as=init, as there is little value in it and we cannot really test this

dbus: to make sure that systemd stays controllable during early bootup, register our services on our own micro usb server in addition to the bus
