Patch for usr.sbin/ngctl/dot.c

The output of "ngctl dot" is suitable for small netgraph networks. Even moderate complex netgraph setups (about a dozen nodes) are hard to understand from the .dot output, because each node and each hook are shown as a full blown structure.

This patch allows to generate much more compact output and graphs by omitting the extra structures for the individual hooks. Instead the names of the hooks are labels to the edges.
