samples: wifi: shutdown: Fix build errors

Shutdown sample assumes default nRF70 mode is scan and doesn't support
any other mode. With the migration to upstream scan only is limited to
nRF7000 shield, so, remove other combinations.

Also, add nRF7000 with 5340 as this was the main usecase for testing
this sample.
