cmd/fpkg: call app in-process
Wrapping fortify is slow, painful and error-prone. Start apps in-process instead.

fortify: improve handling of RevertErr
All this error wrapping is getting a bit ridiculous and I might want to do something about that somewhere down the line.

app: defer system.I revert
Just returning an error after a successful call of commit will leave garbage behind with no way for the caller to clean them. This change ensures revert is always called after successful commit with at least per-process state enabled.

app: expose single run method
App is no longer just a simple [exec.Cmd] wrapper, so exposing these steps separately no longer makes sense and actually hinders proper error handling, cleanup and cancellation. This change removes the five-second wait when the shim dies before receiving the payload, and provides caller the ability to gracefully stop execution of the confined process.
