to include commit wrapper script: workaround kernel limitation in shebang line length

http://stackoverflow.com/a/10826085

use dream branch from slapos when installing testnode
  for "wrapper script: workaround kernel limitation"
use dream_distributor branch for erp5.util

Conflicts:
	software/erp5testnode/software.cfg

with python 2.6 support that can be still required for initial setup of SlapOS.

even though there are install_requires and setup_requires...

Also move mariadb buildout instance profile to dynamic template.

{{- parameters.project_public_folder -}} prevents newline.
