tools/memory-model: Make scripts take "-j" abbreviation for "--jobs"
The "--jobs" argument to the litmus-test scripts is similar to the "-jN" argument to "make", so this commit allows the "-jN" form as well. While in the area, it also prohibits the various forms of "-j0". Suggested-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Paul E.
