meson.build: Fix glib -Wno-unused-function workaround

Browse source 
We want to only enable '-Wno-unused-function' if glib's version is
smaller than '2.57.2' and has a G_DEFINE_AUTOPTR_CLEANUP_FUNC()
implementation that doesn't take into account unused functions. But the
compilation test isn't working as intended as '-Wunused-function' isn't
enabled while running it.

Let's enable it.
