[PATCH 3/3] linux: xf86OpenConsole: Don't detach from tty when running on the active tty

[Hans de Goede]

Detaching from the tty makes little sense when asked to run on the same tty
as we're started from. So automatically assume -keeptty in this case.

This is useful to do because when not running as root the server can only make
various VT related ioctls when it does not detach from the tty.
