Build stub package, which prevent some real package get installed. This
of course make some functionalities unusable, but this is a spirit of
minimal template - make it as featureless as possible.

+%description
+Placeholder package, which provide ghost dependencies for qubes-core-vm to
+minimize number of packages installed in the minimal template. Note that each
+of those dependencies is required for some functionality, so without installing
+some real package (minimal replacement?) some functionality will be missing. At least those:
+ - graphical updates
+ - be a target of qvm-open-in-vm
+ - be a DisposableVM template
+ - context menu "Send to VM" entry in nautilus
+ - graphical notifications
+ - sending application icons to dom0 (no fancy icons in dom0 menu)
+ - will not work as netvm
