Alberto Bertogli 910c6e9cc9 test: Add workarounds for dovecot 2.3
The current dovecot config for integration test t-11-dovecot is not
compatible with dovecot 2.3. There are some new services which want to
change the group owner for some files to the default, and that does not
work when run as non-root.

The errors look like:

  master: Error: service(stats): chown(/tmp/chasquid-dovecot-test/run/stats-writer, 4294967295, 127) failed: Operation not permitted
  master: Error: service(imap-hibernate): chown(/tmp/chasquid-dovecot-test/run/imap-hibernate, 4294967295, 127) failed: Operation not permitted
  master: Error: service(dict): chown(/tmp/chasquid-dovecot-test/run/dict, 4294967295, 127) failed: Operation not permitted
  master: Error: service(dict-async): chown(/tmp/chasquid-dovecot-test/run/dict-async, 4294967295, 127) failed: Operation not permitted
  master: Fatal: Failed to start listeners

(127 is the "dovecot" user)

So this patch adds some config settings to set the group manually for
these services, which is backwards compatible with 2.2.

Eventually we will stop supporting 2.2 for tests, at which point we can
change to just setting default_internal_group.
