- rework pkg-install and pkg-message [1]

- install postfix specific mailer.conf.postfix into DATADIR [2]

- make EAI the default, postfix will reject messages if build
  w.o. EAI and compatibility_level is set to a value >=1 [3]

- use new notation instead PATCH_DIST_STRIP

- bump PORTREVISION

1) detect if the port is installed without TERM, in this case
   do not ask the to make postfix the default mailer and respect
   the env POSTFIX_DEFAULT_MTA. This helps tools like salt,
   ansible, cfengine and puppet during the first package installation.
