man: Fix RFC 1918 network prefix lengths
According to RFC 1918, the following IP prefixes are reserved for
private internets:
10.0.0.0/8
172.16.0.0/12
192.168.0.0/16
This PR fixes the prefix lengths in references to private networks
("RFC 1918 networks", "the standard private IP address ranges").
The changes are limited to man pages.

This option is useful in the case that the packet aliasing host has both
registered and unregistered subnets on different interfaces.
