omarchy-settings: keep the Mac initramfs hooks on aarch64

Apple Silicon Macs install the aarch64 package too, and an unconditional
HOOKS= line would replace their asahi hooks. Apply Omarchy's HOOKS line only
when the incoming hooks lack asahi, in whichever drop-in carries it, and
rebuild omarchy-settings (4.0.4-3) so existing installs get the fix.
