wt-status: don't flush before running "submodule status"

This is a holdover from the original implementation in
ac8d5af (builtin-status: submodule summary support,
2008-04-12), which just had the sub-process output to our
descriptor; we had to make sure we had flushed any data that
we produced before it started writing.

Since 3ba7407 (submodule summary: ignore --for-status
option, 2013-09-06), however, we pipe the sub-process output
back to ourselves. So there's no longer any need to flush
(it does not hurt, but it may leave readers wondering why we
do it).
