  [fuchsia] Simplify connecting to service
  
  Use helper function that automatically opens the service root and
  connects to the named service inside. This avoids the need to keep a
  handle around. This is being done as part of the io2 migration, where
  opening the /svc directory requires PERM_READABLE in most cases.
