tests: drivers: build_all: ieee802154: Add overlay for native_sim and 64

The native_sim has already been added to the test cases of
`drivers.ieee802154.build.external` is not being appropriately
processed because there is no corresponding overlay.

Create an overlay as an alias of native_posix.overlay.

Also, add the native_sim/native/64 platforms in the same way.
