mjit_worker.c: promote mjit_copy_job from function
-local variable to global variable.
Consider this case:
1. MJIT worker: dequeue ISeq (stop_worker_p was still FALSE)
2. Ruby thread: call Kernel#exec, which calls mjit_finish(FALSE),
sets `stop_worker_p = TRUE`, and fires RUBY_VM_CHECK_INTS() once
3. MJIT worker: register copy job, but found stop_worker_p is TRUE.
set `worker_stopped = TRUE` and the thread stops.
4. Function-local job variable expires by the thread stop (this is eliminated by this commit)
5. Ruby thread: find `worker_stopped` becamse TRUE, start Kernel#exec.
Kernel#exec fails but exception is rescued.
6. Ruby thread: call RUBY_VM_CHECK_INTS. copy job is dispatched but job variable
is already expired.
