Bug#743015: xinit does not handle starting X correctly

[Vladimir K <pzs-fs@yandex.ru>]

I've tested the change. 
When using startx, X session is correctly started at the same VT, but some features are missing. 
I.e. I can not edit Network manager connections. (works when I login with lightdm)

$ loginctl show-session $XDG_SESSION_ID

May be Type=tty is to blame? Where and how this can be changed?

I also suggest this fix to xserverrc:

exec /usr/bin/X -nolisten tcp `ps -o cmd -p 1 | grep -q '/bin/systemd' 2>/dev/null && echo vt$XDG_VTNR` "$@"

This way we do not hurt xsession if systemd is not used.
