Drop the /tmp/cce-status-interface-adjust-mode flag file

adjust-position-mode created and removed a fixed-name file in shared
/tmp that nothing reads. The bar learns the mode from the status
socket's adjust topic. The file only added a path another local user
could pre-create. The write and its three cleanup calls are gone.
