[gnome-builder/gnome-builder-3-26] meson: use 'meson introspect'

    meson: use 'meson introspect'
    
    mesonintrospect was failing to execute properly due to an
    internal meson error. This makes things work similar to how
    it works for us on master (with the C port of meson plugin).
    
    Fixes #257
