Make Hook the default OSIE:

With the recent update in Hook to publish the kernel and initrd
we can make make hook the default in the sandbox. Original OSIE
can still be used by updating deploy/compose/.env and setting
OSIE_DOWNLOAD_URL to an OSIE URL and TINKERBELL_USE_HOOK to false.
Currently only an x86_64 Hook is published so only x86_64 machines
can be provisioned with the sandbox using Hook.
