MDEV-27088 adjusted the lf hash tests to have sufficient iterations to catch errors.

The ARM based discussion reached consensus on https://github.com/MariaDB/server/pull/1951

even at bottom of MDEV-27088 test failures where observed.

Comment by Daniel Black [ 2022-04-28 ]

MDEV-28430 continues the long history of aarch64 (and small amount of ppc64le) failures.

Looking at the history the kvm-{fulltest,fulltest2,asan} (regardless of ps-protocol, didn't impact unit tests) test failure on unit.lf stopped in early 2019, with the exception of aarch64 and ppc64le.
