BUILD: applet: fix build on some 32-bit archs

The to_forward field was added to debugging output of applets with commit
62a81cb6a ("MINOR: applet: Add callback function to deal with zero-copy
forwarding"), though it's a size_t printed as %lu, which causes complaints
on 32-bit archs. Let's just cast as %lu.

No backport is needed.
