[gedit/zbrown/deteplification-src: 180/633] build: always require GObject Introspection and vapigen

[Zander Brown <zbrown src gnome org>]

commit 6ebc5f21817f4898a162b765289f584930d79721
Author: Sébastien Wilmet <swilmet gnome org>

    build: always require GObject Introspection and vapigen
    
    The gedit repo contains Python plugins. And the gedit-plugins repo
    contains one Vala plugin.
    
    It simplifies the build instructions.
