[libgda: 3/3] Update SO version

[Daniel Espinosa Ortiz <despinosa src gnome org>]

commit 0213b22e159ef32cb43c56b3cdf3ee9b91ebb671
Author: Daniel Espinosa Ortiz <esodan gmail com>

    Update SO version
    
    Meson uses same rules as for Autotools for SO versioning.
    
    Version 6.0.0 will be API/ABI break; 5.2 branch uses current as 5,
    revision to 1 and age to 1, so new version is current 6, revision
    and age are set to 0.
    
    For meson, we should calculate version = current - age, so set to 6
