[gnome-builder] prefs: add preference to enable jump to last position feature.

[Christian Hergert <chergert src gnome org>]

commit 429698975c7153176decd2c48aadf9acd83f2e8c

    prefs: add preference to enable jump to last position feature.
    
    This requires at least performing a `make install-gsettings-schemas or
    you will get a crash when hitting the gsettings code.
    
    `make install` works too.
