Previously, if the callout binary (i.e. sd-pull, sd-import) failed
gracefully, we'd return its exit status from the event loop and thus
from run_callout(). Of course, exit status is a positive number in the
event of failure. Which means that we completely ignore the callout
binary failing, and instead continue using whatever it managed to
download before failing.
This is bad for obvious reasons, not the least of which is installing
a half-downloaded OS. This also means that we would completely ignore
failed signature checks 😬️
