airskiff: Sequence Airship components

Currently, Airskiff does not deploy Airship components in sequence. This
can lead to timeouts due to limited resources, namely when deploying
Shipyard. This commit changes the Airship components to a sequenced
deployment to avoid timeouts due to limited resources.
