installation: change table TYPE to ENGINE in SQL
installation: change table TYPE to ENGINE in SQL

* In CREATE TABLE SQL statements, use ENGINE instead of deprecated TYPE for
  better compliance with higher MySQL versions.

* Remove forcing of PACK_KEYS along the way, since the usual MySQL default
  behaviour is very nice already.

* Cherry-picked from fbbfaa66645e3cb0b9d37c7abf083f76e3e31344.
