-z nodelete breaks the libresourceplugin module usage in the resources.c test, which expects to be able to unload it. Make the Meson build match what the autotools build does: only pass glib_link_flags to the headline libraries (glib-2.0, gio-2.0, gobject-2.0, gthread-2.0, gmodule-2.0) and omit it from all other build targets. https://bugzilla.gnome.org/show_bug.cgi?id=788771
