sshd: adjust /etc/ssh and includes dir permissions

There is no reason these should have such restrictive permissions, and missing the execute bit appears to be a mistake. Let /etc/ssh keep the mode from the package (0755). Use the same for the includes directory.

(I will manually change /etc/ssh back to 0755 once this is merged.)
