[Maxima] Elapsed time per testfile?

[Raymond Toy]

Anyone interested in showing the elapsed time (real and CPU) for each
testfile in the testsuite?  Something like:


> Running tests in rtest_taylor: 144/144 tests passed (not counting 12 expected errors)
>   using  44.853 secs (37.155 CPU sec).
> Running tests in rtest_dot: 55/55 tests passed
>   using  0.060 secs (0.038 CPU sec).

I made it two lines to make it easier to see, but one line would be
nicer, except that some lines are already quite long (like the
rtest_taylor line above).
