Further improvements on extra services configured in master.cf

As promised in PR #75, here's a further (and hopefully final)
iteration of the master.cf service handling:

- Bring dovecot and policyd-spf configuration in line with the
  extras_services item added in PR #75
- Remove policyd-spf configuration again from services.jinja,
  handle this in master.cf instead, where it was before
- Allow for completely custom services to be added via a pillar
  definition in postfix:master_config:services
- Fix legacy dovecot argv example in pillar.example: The example
  showed the extra_args being defined as part of the argv
  parameter, something that would clash with the actual code and
  result in a duplicate '-d ${recipient}' definition in the config.
