[polari] Update .gitignore

[Florian Müllner <fmuellner src gnome org>]

commit 3a4729b372c0d47c1947f16a0d7b3db048e446ba
Author: Florian Müllner <fmuellner gnome org>
Date:   Fri Apr 19 13:48:14 2019 +0200

    Update .gitignore
    
    The autotools compatibility stuff added in commit d71ed111971 is long
    gone, so no need to account for Makefile.
    
    Exclude gnome-builder's .buildconfig and the generated po template.
