No objections from my side.

The only reason for me to enable dlmalloc from time to time was that I
suspected some bug in the allocator, but it never actually turned out to
be a bug in the allocator. Now with Kasan we have far better memory
debugging facilities than back in those days, so yes, I think it's time
to schedule removal of dlmalloc.
