win32: close the handles associated with a spawned child process

Probably not a big deal because at this point, the call is only used when
spawning a daemonized server.  In that case, the parent process goes away first,
so it won't prevent the child from being cleaned up.

  $ cat <<'EOF' >> "$HGRCPATH"
  > [extensions]
  > convert =
  > [templates]
  > l = '{rev}:{node|short} p={p1rev},{p2rev} m={manifest} f={files|json}'
  > EOF

  >     if [ "$?" != 1 ]; then
  >         echo '*** BUG: hash changes on convert ***'
