[PATCH 2/4] search: remove auto-start for async_mset

[Eric Wong <e@80x24.org>]

Only public-facing daemons use it, currently, and all
public-facing daemons will pre-spawn it as early as feasible.
lei will need it eventually to handle queries requiring C++,
but I'm not certain what path to take with lei, yet...
