Bug 36232: Fix error in DBRev dealing with OAI-PMH:AutoUpdateSetsEmbedItemData typo

This patch fixes the case of the wrong syspref variable co-existing with
the good one.

OAI-PMH:AutoUpdateSetsEmbedItemData is the only case, as the rest of the
mispelled ones are just case fixes, which would not trigger the same
situation as the `systempreferences` table collation is
case-insentitive.

To test:
1. Run:
   $ ktd --shell
  k$ koha-mysql kohadev
   > INSERT INTO systempreferences VALUES ('OAI-PMH:AutoUpdateSetEmbedItemData',0,'','','YesNo');
   > UPDATE systempreferences SET variable = 'IllCheckAvailability' WHERE variable = "ILLCheckAvailability";
   > INSERT INTO systempreferences VALUES ('IllCheckAvailability',0,'','','YesNo');
=> FAIL: The last command fails because the good and wrong values cannot
coexist
2. Set the version to a prior one:
   > UPDATE systempreferences SET value="23.1200004" WHERE variable like 'version';
3. Run:
  k$ updatedatabase
=> FAIL: You get this error:
ERROR: {UNKNOWN}: DBI Exception: DBD::mysql::db do failed: Duplicate entry 'OAI-PMH:AutoUpdateSetsEmbedItemData' for key 'systempreferences.PRIMARY' at ...
4. Apply this patch
5. Repeat 3
=> SUCCESS: It works!
