lei: commit store on interrupted partial imports

This change prevents lingering shard and git-fast-import
processes from remaining after interrupted "lei import" (and
similar).  It also reduces the likelyhood of data-loss in case
of subsequent abnormal termination of the daemon.

I think this is the least surprising way to handle users
prematurely aborting imports or other similar operations which
write to lei/store and will result in reduced bandwidth waste
for users with intermittent connections.  This is because the
lei/store processes may be shared by parallel "lei import"
callers, and commits done by any "lei import" caller will
inevitably trigger writes for all of them.

t/lei-watch: add diagnostics for failure

I just got a difficult-to-reproduce failure, here; so there's
still some issues with the up-to-dateness of the inotify watcher.

lei_to_mail: only run lms_write_prepare for IMAP+Maildir

Mail synchronization in lei_to_mail only works for IMAP and

input_pipe: account for undefined {sock}

It's possible for ->event_step to fire twice due to ->requeue
with EPOLLET (but not EPOLLONESHOT).  So account for that and
avoid causing event loop errors as a result.
