Subject: busctl: flush stdout after dumping data
X-Git-Tag: v222~34

busctl: flush stdout after dumping data

Running `busctl monitor` currently buffers data for several seconds /
kilobytes before writing stdout. This is highly confusing if you dump in a
file, ^C busctl and then end up with a file with data of the last few
_seconds_ missing.

Fix this by explicitly flushing after each signal.
