modern-gtk2: Require Gtkmm version 2.24 (!17)

Require the latest minor version of gtkmm2, released back in 2011 [1].
This is the first step in porting to Gtk3 [2].  This drops GParted
support for very old but still supported distributions:
    Distribution      EOL        Gtkmm
    RHEL / CentOS 6   2020-Nov   2.18.2
    SLES 11           2022-Mar   2.14.1
