[PATCH xinit] startx: Pass -keeptty when telling the server to start on the current tty

[Hans de Goede]

Detaching from the tty causes systemd-logind to refuse service to the xserver,
the xserver already tries to detect that it is being asked to run on the
current tty and then automatically enables -keeptty, but this code fails if
all of stdin, stdout and stderr are redirected to a file. So explicitly tell
the xserver to not detach when we're telling it to run on the current tty.
