 When running `qemu-system-x86_64 -machine accel=hvf ...` on macOS Big Sur,
 qemu exits with `qemu-system-x86_64: Error: HV_ERROR`.  After performing
 'ad-hoc signing' and giving it the `com.apple.security.hypervisor`
 entitlement, it works.  Perhaps we need a `post-destroot` that runs
 `codesign`.  Here is what I did.
