[MariaDB developers] PR#2779: Fix merge commit 5ea5291: No test file or result files should be executable

Hi Sanja! Did you notice my PR https://github.com/MariaDB/server/pull/2779? I tagged you about a minor bug in you previous merge. I was hoping you would notice it and review that PR, but Daniel Black jumped on it. I am asking now because it seems the exact same thing happened for mysql-test/main/lowercase_table2.result in your commit fecd78b8378 from November 8th, so I thought I'd send an extra email now to ensure you are aware of this happening. - Otto
