Subject: [PATCH] fail2ban: fix dovecot filter's journalmatch

The dovecot filter config distributed with fail2ban watches for log
entries with a journalmatch filter of "_SYSTEMD_UNIT=dovecot.service",
but NixOS's Dovecot runs as dovecot2.service. Fix the journalmatch
config to match NixOS's Dovecot.
