gnome-extra/gnome-calendar-3.30.1: block evolution-data-server-3.32

It tries to define its own (g_autoptr) autocleanup stuff for eds
structures, which now conflict with the eds upstream provided ones
in 3.32. As there will be a 3.32 bump for gnome-calendar, which
solves it, just block the newer e-d-s there to enforce in-sync
updates and avoid build failures for those that try to mix keywords
(and suggest what more to put into the mix).
