arm64_download script waits for VM to boot before finishing.

It may take an unknown amount of time to boot.

Also, add `set -e` to the script to simplify error handling.

PTAL.  We now keep trying SSH until it fails.

platform_tools/barelinux/bin/arm64_download:9: set -e
Note that "set -e" can have its pitfalls.  See

Hopefully it will work as desired in this case.

You may wish to pull that change into a separate CL, in case you need to revert
it separately... but I'll let you decide if that's worth the hassle.
