proxy: followup to last-queued-change metric

Browse Source 
Fixes two small issues with the metric added in #90175:

1. Bump the timestamp on initial informer sync. Otherwise it remains 0 if
   restarting kube-proxy in a quiescent cluster, which isn't quite right.
2. Bump the timestamp even if no healthz server is specified.
