test: Specify node-selectors in BGP configmap
test: Specify node-selectors in BGP configmap

We recently had a regression
(https://github.com/cilium/cilium/issues/16340) that occurred when the
user specified node-selectors in their BGP configmap. The node-selectors
were not picked up due to the bug that was fixed in
https://github.com/cilium/cilium/pull/16341.

This commit is to add regression testing for the BGP integration.
