[bug#42899] [PATCH 03/10] services: dovecot: Use modules via symlink to system profile.

[Alexey Abramov]

* gnu/services/mail.scm (%dovecot-activation): Link the location with multiple
plugins (dovecot-pigeonhole, etc), to a place where dovecot can find them.
* gnu/services/mail.scm (dovecot-configuration): Use the symlink.
