The expression `host_package_build.value_or(*fallback_host_build);` to
select between two optionals after knowing one is set is invalid. In the
case where `fallback_host_build` is missing and `host_package_build` is
present, `fallback_host_build` is still dereferenced to supply the
argument to `value_or`, even if it is ignored by the implementation.
Issue observed by dsk@ using the following configuration to `cvd load`:
