sources: consider only reachable orphans for selection

Browse source 
Ignore orphan sources that are unreachable (but still have usable stats)
to have a quick and consistent source selection between orphans.

This also fixes the "Unknown local refid in orphan mode" error appearing
when a selected orphan source is removed, as the source is marked as
unreachable and the selection runs with disabled NTP instance before the
source instance is actually removed.
