services: dovecot: Copy dovecot.conf to /etc/dovecot.

Browse source 
Many Dovecot utilities compiled with assumption of ‘/etc/dovecot/dovecot.conf’
existence.

* gnu/services/mail.scm (dovecot-shepherd-service): Move config generation.
Invoke ‘dovecot’ without ‘-c’ flag.
(%dovecot-activation): Copy ‘dovecot.conf’ to ‘/etc/dovecot’.
(dovecot-service-type): Make ‘%dovecot-activation’ non-constant.
