To uninstall buildd just follow these instructions.
/debian/stretch/main///install/index.html Daemon for automatically building Debian binary packages from Debian sources Debian 9.0 devel 0.73.0-4
sudo apt-get remove buildd
Which will remove just the buildd package itself.
sudo apt-get remove --auto-remove buildd
This will remove the buildd package and any other dependant packages which are no longer needed.
If you also want to delete your local/config files for buildd then this will work.
sudo apt-get purge buildd
Or similarly, like this buildd
sudo apt-get purge --auto-remove buildd
