Patch from John S Gwynne <jsg@…> for malloctest. His comments:

I have a few patches for the efi332 bsp. If you let me know when you
expect the next snapshot release, I will try to have them to you
before then. Also, the malloctest has some problems that I would think
would prevent it from running on almost any platform. I have enclose
patches below to fix (1) Task_id and Task_name dimensioning, (2) end
of test message, (3) the amount of memory malloc'ed, and (4) retry on
unsuccessful (out of memory) molloc's.
