buffet: Abort all the limbo commands.

On startup, especially after unexpected device restart,
there might be commands which cloud regards as still running.
The safest option is to abort them immediately on startup,
but later on we can give implementation a chance to resume
those commands.

BUG=chromium:420573
TEST=cros_workon_make buffet --test && manual testing.
