[LTP] [PATCH v3 5/5] ima_violations.sh: require kernel v6.14 for minimizing violations tests

Hi Mimi,

I would prefer this to be squashed into "ima_violations.sh: additional
open-writer violation tests" commit, which adds this incompatibility.

But it's a minor detail, therefore I merged whole patchset as is.

Thanks!

Kind regards,
Petr
