Fix line break in Cisco show bgp ipv4 uni sum

Line break in Cisco parser for show bgp ipv4 unicast summary caused
exception. This happens when the IP address is longer and newline
is inserted to allign columns. And this happens especially when
somebody uses IPv6 peer to transport IPv4 routes.

Fix line breaks using code for IPv6 also in IPv4 handling
code.
