The `mount-tester` image is currently used as a base layer for other test images (like `mounttest-user`) which perform uid/gid changes. However, the binary built in here just follows local umask, and currently is ``` -rwxr-x--- 1 root root 2052704 May 19 2016 mt ``` This commit adds an explicit chmod on the binary to make sure uid/gid tests can still run it as "others".
