Subject: [PATCH] lib/open: use db struct as talloc ctx for
 choose_database_path

The extra talloc struct "local" was left over from before the notmuch
struct was allocated earlier. Having the notmuch struct available in
this function will allow more flexibility to track the configuration
variations (e.g. split vs. non-split).
