omarchy-settings: ship the full set on aarch64 for runtime-profile sources

A source with default/settings-runtime-profile decides at runtime which
platform-specific files apply, so its aarch64 package now gets the same files,
backup and optdepends as x86_64: the Thunderbolt request and the memory stack
stay, and its HOOKS files ship as they are. The check that a Mac's asahi line
survives still runs on every aarch64 build. Older sources, including the pinned
v4.0.4, keep #380's aarch64 package: Thunderbolt removed, the HOOKS line guarded
for asahi, the memory stack stripped. The keyboard backlight unit first-run
enables ships whenever the source has it.

pkgrel 4 so the recipe change builds: edge already holds 4.0.4-3 on both
architectures. The payload built from v4.0.4 is unchanged.
