Changing sorting of --no-task-tracking to alphabetize it

I have no idea why I thought that this was properly alphabetized
when I added it...  Did I originally call it something different?
Adding --[no-]task-tracking to the man page

Also updating the man page test so that it runs in qthreads rather
than fifo mode in order to trip over it sooner in developer testing.

Fix man task tracking

[trivial and fixes last night regression, not reviewed]

This commit adds a man page entry for the new --task-tracking
flag. It also changes the SKIPIF for the man page verification
flag so that it runs in qthreads rather than fifo mode, in order
that developers are more likely to run into it sooner rather than
later.

In putting this together, I noticed that I had failed to alphabetize
the flag correctly even though I remember thinking about it, so
fixed that while here as well.
