Bug 17292 - Use of DBIx in updatedatabase.pl broke upgrade

A recent change in the 'subscription' table structure highlighted a
problem in a DBRev upgrade (3.23.00.006). As it adds a new column, when
upgrading from (say) 3.20.00.000 the code/schema (correctly) expects the
subscription.itemtype column to exist. But it is not created until DBRev
16.06.00.025.

To reproduce:
- Have a clean 3.20.00 DB loaded into kohadevbox
- Checkout current master
- Run:
  $ perl installer/data/mysql/updatedatabase.pl
  => FAIL: The upgrade procedure fails due to missing colum.

  The solution: rewrite the updatedatabase.pl entry using plain DBI
