Fix sort_show_route to work with multi-line BGP community lists
I encountered a bug in the script sort_show_route that manifests when the show route dump includes bgp community list spanning multiple lines.
Example:
5.182.20.0/24 unicast [R1111x11 2024-11-06] * (100) [AS1111i]
via 111.111.0.228 on ve0
Type: BGP univ
BGP.origin: IGP
BGP.as_path: 1111 2222
BGP.next_hop: 111.203.0.228
BGP.med: 2
BGP.local_pref: 100
BGP.community: (0,16509) (1,1089) (64700,8860) (65400,0) (65400,65400) (1121,65000) (1120,2)

Multi-line community list are valid so I changed the regexes in the script so that it works with them as well.
While I was at it I also deleted unnecessary/invalid semicolons at the end of some lines :)
