omarchy-settings-dev: check for the detector copy on aarch64 only

The guard and its detector copy now ship on aarch64 only (#691), so the check that 00-omarchy-hooks.conf has its detector failed every x86_64 build from a source that carries the HOOKS baseline. x86_64 keeps the busybox line without a detector. Same scoping as omarchy-settings in #638.
