Make constructor-based resource registration malloc free

We need to do this because constructors run before main() and
thus before any call to g_mem_set_vtable, making it impossible to
use that function if constructors call g_malloc.

We do this by making the constructors just register the static data
for lazy registration, doing the lazy registration when using
the global resource set.
