In a streaming replication setup that was created without replication
manager (`repmgr`), the `stat_wal_receiver` collector does not return
any metrics, because one value it wants to export is not present.
This is rather overly opinionated. The missing metric is comparatively
uninteresting and does not justify discarding all the others. And
replication setups created without `repmgr` are not exactly rare.
This commit makes the one relevant metric optional and simply skips it
if the respective value cannot be determined.
