modules: fix reading proxy-node out GVariants

GVariant is instructed to store a 64-bit unsigned integer (mode "t")
but we pass it a pointer to a pointer to read this value out,
which will crash in 32-bit architectures, as the pointer doesn't have
enough bits and g_variant_lookup therefore corrupts the stack.
