Subject: start-stop-daemon should unbuffer its stdout/stderr

Date: Fri, 28 Feb 2025 10:18:21 +0000

Package: dpkg
Version: 1.21.22

start-stop-daemon it can fail to print its output due to daemonising
with data still in the stdio buffers.  ISTM tht the output should
always be timely, so unbuffering the streams is the right fix.
