port patch

Kafka 4 removes Zookeeper support and uses KRaft mode by default now.
This impacts upgrade procedure.

Changes in the port: 
- update net/kafka to 4.1.1
- remove KAFKA_DBDIR_KRAFT and KAFKA_CONFIGS_KRAFT, use usual KAFKA_DBDIR and
KAFKA_CONFIGS instead.
- remove pkg-message TBD
- remove JAVA sub pointing to a particular jdk version. Use ${PREFIX}/bin/java
instead to be able to switch java version via standard javawrapper if needed.
- fix build errors for ETCDIR reinplace by setting exact files to change
- enrich log.dirs reinplace with broker.properties and controller.properties
- add plugin.path reinplace for connect-standalone.properties and
connect-distributed.properties as a hint for users
- merge all MKDIRs to save some cpu cycles during build
- update rc scipts:
-- log4j.properties -> log4j2.yaml
-- use ${PREFIX}/bin/java just like described above
-- set proper default kafka_connect_config in kafka_connect.in depending on
mode


How I see the 3.9.1 to 4.x upgrade:
- repocopy net/kafka to net/kafka3
- add CONFLICTS to both net/kafka3 and to the patch posted here
- add UPDATING entry telling to:
-- install net/kafka3 instead of net/kafka
-- switch kafka to KRaft mode if it's not
-- stop kafka
-- install net/kafka instead of net/kafka3
-- rename/copy KAFKA_DBDIR_KRAFT dir (/var/db/kafka-kraft by default) to
KAFKA_DBDIR (/var/db/kafka by default)
   OR
   adjust `log.dirs` in server.properties, broker.properties and
controller.properties to point it to old existing current db dir.
-- review/copy params for old KRaft mode configs from ${ETCDIR}/kraft
(/usr/local/etc/kafka/kraft by default) to ${ETCDIR} (/usr/local/etc/kafka by
default)
-- review official instruction
https://kafka.apache.org/41/getting-started/upgrade/ and start new kafka

I'm asking for testing and any input about proposed upgrade procedure.
