bgpd: fix large route-distinguisher's format

This commit is about #5629 's issue.
Before this commit, bgpd creates format string of
bgp-route-distinguisher as int32, but correctly format
is uint32. current bgpd's sh-run-cli generate int32 rd,
so if user sets the rd as 1:4294967295(0x1:0xffffffff),
sh-run cli generates 1: -1 as running-config. This
commit fix that issue.
