[gnome-desktop] Avoid duplicating version number in configure.in

[Pascal Terjan <pterjan src gnome org>]

commit 84d17f73a92fe49eb2f79ae7d3b0e521f852e06e

    Avoid duplicating version number in configure.in
    
    2.28.1 was released with GNOME_MINOR set to 0 so gnome-about displays
    2.28.0 instead of 2.28.1
    
    To avoid this issue this patch only defines the values once
