Updating file permissions for XDMoD's bin directory (#1510)

* Updating file permissions for XDMoD's bin directory

These changes are to address TrustedCI 6.2.5, tracked at
https://app.asana.com/0/15230011293655/1188274656222921 .

We're updating the permissions of files in XDMoD's `bin` directory from `0755`
to `0750` to ensure only users in the xdmod group ( or root ) can execute these
files.
