Add support for OCI annotations

Browse Source 
Annotations do not do anything by default but get passed through to the runtime,
which can be useful. I never metadata I didn't like...

Also fix sysctl to be a map in the validation, not an array. I can't see any
examples using this in LinuxKit, but this matches OCI so is correct.
