[gnome-desktop-testing/wip/smcv/help] Produce less confusing --help output

[Simon McVittie <smcv src gnome org>]

commit 2f80b83af397990461e887808db91971c2c66a57

    Produce less confusing --help output
    
    --dir wants an argument, and --first-root does not. Adjust the
    GOptionEntry placeholders accordingly.
