gitlab-ci: fix pipeline error "libhandy cannot find vapigen"

Add following configure options to our libhandy subproject:

-Dlibhandy:examples=false -Dlibhandy:tests=false -Dlibhandy:vapi=false -Dlibhandy:glade_catalog=disabled -Dlibhandy:introspection=disabled

Because Evince does not need any of those features from libhandy and they may cause issues when building, like the one mentioned where libhandy cannot find vapigen (and it's a waste to install it in our ubuntu ci image as Evince does not use vala bindings nor any of the other features).
