Distro._reboot_required(): Fix comparison

The comparison ret != 0 is comparing a Result object against the
integer 0, which is always True since Result has no __eq__ defined.

This commit fixes the bug by comparing ret.status instead, which is
the actual exit code we care about. This satisfies the new
strict_equality mypy rule which enables the comparison-overlap check.
