[PATCH 3/3] v2writable: done: force synchronous awaitpid

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

We need to shut down shards synchronously to reliably release
the inbox write lock when inside the DS event loop (as the
lei/store subprocess is, unlike most v2writable users).

While more testing is being conducted, this seems to fix
long-running `lei import' failures to lei/store.  It seems like
a good idea anyways to ensure exit status of shard workers are
correct before returning from ->done.
