[MariaDB developers] Clean up executable test result files:

Hi! In https://github.com/MariaDB/server/commit/9cb75f333fa2ae816909f95a4e19e6ddac2... Alexander made some test result files executable (look at 100644 → 100755 in git diff). I sent twice a PR to fix this: - Oct 2023: https://github.com/MariaDB/server/pull/2779 - Feb 2024: https://github.com/MariaDB/server/pull/3042 Unfortunately, I can see that on the main branch this is executable again: mariadb-server main+ ± find mysql-test -executable -name *.test -or -executable -name *.result mysql-test/main/lowercase_table2.result Could the next person doing merges fix this tiny annoyance once and for all? Thanks :)
