[gnome-keyring] main: don't call close() with a negative value

[Stefan Walter <stefw src gnome org>]

    main: don't call close() with a negative value
    
    When run_foreground = TRUE, fork_and_print_environment() will return -1,
    which is assigned to parent_wakeup_fd.
    Since we don't want to call close(-1), only close(parent_wakeup_fd) when
    run_foreground = FALSE.
