seqjob registers sched_allocator_run with seqjob_alloc_iface (no accepts
guard, plus its one-bucket plan iterator); its private my_alloc() is
gone. New fixtures pin the intended changes: a reason for every short
host, the bug-1893 shared reason, the host-stage OOM debit release, and
-EINVAL for missing inputs; seqjob's plan is asserted to be one bucket of
one slot. No other test expectation changed.
