bgpd: Always show CIDR mask when displaying routes

Browse Source 
Classful networking has been obsolete for ages and there is currently an
inconsistency between `show ip route` and `show bgp`, where the first
one always displays the CIDR mask while the second one hides classful
network masks.

This commit adjusts the behavior of `show bgp` to always show the CIDR
mask for a route, even when it is classful.
