Subject: [PATCH] cmd/godoc: start RunIndexer synchronously when index is
 present

Until the index is read completely, search requests will serve
an "indexing in progress" message. We make this synchronous
to allow the index to be read completely before starting to serve
requests.

Fixes golang/go#24965
