do not expect user input if stdin is redirected

Browse source 
If GZDoom is built on a POSIX system without the GTK frontend and not
run from a KDE session, an IWAD picker is presented on the terminal
and expects the user to select a game wad. However, if stdin is
redirected, this won't work, so start with the default IWAD instead.
