    flatpak: Pin gexiv2 and exiv2 dependencies to fix build
    
    The flatpak build currently fails because of gexiv2 build failure, which is
    a problem for our contributors and among others breaks our CI pipeline. The
    potential fix is available already for a couple of days on
    https://gitlab.gnome.org/GNOME/gexiv2/-/merge_requests/63 but not yet merged.
    Let's temporarily pin the gexiv2 and exiv2 dependencies to the stable branches
    to fix those issues.
