folks build test failures with glib 2.80

• Debian Unstable
• folks 0.15.9

If I try to build folks 0.15.9 with glib 2.80.0 and gobject-introspection 1.80.1, I get a bunch of build test failures. This does not happen with glib 2.78.4, which is what is actually in Debian Unstable today. I figured this out while trying to figure out why the build tests occured on Ubuntu 24.04 LTS but not on Debian Unstable.
