net-mail/fetchmail: Add instance systemd.service file (fetchmail@.service)

In certain use-cases, it is necessary to run several instances of fetchmail
in parallel (e.g. monitoring numerous accounts via IMAP-IDLE).

This adds a systemd fetchmail@.service file, allowing the user to configure
fetchmail in the following way:

 $> systemd enable fetchmail@INSTANCE_NAME

 /etc/fetchmailrc-INSTANCE_NAME
 /run/fetchmail/fetchmail-INSTANCE_NAME.pid
 /var/lib/fetchmail/.fetchids.INSTANCE_NAME

(cherry picked from commit de1ce79c92c4fce45bd44400d39419663643549d)
