queue.scm: Split postfix-service-type into {local,internet}-postfix-service-type

Also add those to `Makefile` as separate targets.

BONUS: better naming of Guix targets in `Makefile`.  Instead of
       `all-{packages,services}`, it is now `guix-{packages,services}`,
       as there are other packages being built that do not belong to
       Guix, and maybe more services in the future.

+        Run the Postfix MTA.
+
+        This is the top-level system service for Postfix.
+
+        It includes:
+        - populating /etc/postfix/ with read-only configuration files;
+        - the user and groups used by Postfix when handling email delivery;
+        - the special setgid binaries for daily usage, such as \"sendmail\";
+        - the Shepherd service for starting, stopping and *reloading* the
+          service without restarting it;
+        - the activation script for creating the required directories and
+          configuring them with the correct permissions;
+        - the binaries in the system profile so that one doesn't need to explicilty
+          include the package when the service is already enabled.
+
+        An extension to the log-rotation service isn't included: the default
+        rottlog configuration already includes /var/log/maillog in its routine,
+        so it is kept out.
+
+        The defaults of <postfix-configuration> provide sane default values for
+        most things, such as group names, data and queue directories, etc.  When
+        used as-is, it creates a Postfix server that sends email from local users
+        of the domain provided by \"/etc/hostname\".")))
