LP#1613374 - Set item status to 'Canceled Transit' when transit is canceled.

I opened a separate bug report on this issue (bug 1613374) before realizing
bug 1306666 was reported.  This commit creates a new 'Canceled Transit' status
that signals to staff what happened to an item when a transit is aborted/canceled.
