Denis Protivensky 1c48950e1f MDEV-30536: Fix Galera bulk insert optimization MTR test
After closing https://github.com/codership/galera-bugs/issues/947,
Galera now correctly certifies table-level keys, which made bulk
insert work again.

The corresponding MTR test is made deterministic and re-enabled.

Requires Galera 26.4.19
