t: update job.exception output checks

Problem: In the near future, the job.exception output in flux-core
will change, resulting in failures in tests that expect a specific
format.

Update the job.exception parsing in t1006-qmanager-multiqueue.t and
t1024-alloc-check.t to be more flexible to future output changes.
