annotations: Add missing hypervisor control annotation

Add missing annotation definitions for a hypervisor control binary:

- `io.katacontainers.config.hypervisor.ctlpath`
- `io.katacontainers.config.hypervisor.hypervisorctl_hash`

This is a partial cherry-pick. The test changes in asset_test.go
have not been included since the tests structure has changed in
newer branches.
