filtering: wait for the data-sending process to terminate too 

When piping the buffer (or the marked region) to an external command,
we should wait not only for the external command to terminate but also
for the data-sending process, so that it will release its resources.

This fixes https://savannah.gnu.org/bugs/?54499.
