Invalidate the display rebuild marker before repairing its drop-in

A pending migration must rebuild after restoring its missing display configuration even when another user previously completed the machine-wide rebuild. Remove the fixed marker before writing the drop-in so failed writes and builds remain retryable. Fresh installation already rebuilds after hardware setup through the ISO finalizer.
