callout: ddb: resolve symbol of callout function

In the ddb show callout function try to resolve the symbol of the
callout function to improve debugging.  In my case I went through
various callouts from show ktr to check what they were and this saved
me opening lldb/gdb next to it (and still having the old kernel as
the panic to debug was upon reboot).
