[PATCH maint] start_command: flush buffers in the WIN32 code path as well

[Johannes Sixt <j.sixt@viscovery.net>]

From: Johannes Sixt <j6t@kdbg.org>

The POSIX code path did The Right Thing already, but we have to do the same
on Windows.

This bug caused failures in t5526-fetch-submodules, where the output of
'git fetch --recurse-submodules' was in the wrong order.

I think this is the correct fix.
