Reset per-pkg app-ops for runtime permissions

... on every boot.

These should never have been set, but we allow settings them via the
shell.

- Also previously a bug set per-pkg app-ops.
- Also set the app-op correctly when a fg/bg permission looses it's bg
permission.

Test: Set per-pkg app-opp. Rebooted and saw log message.
