description:
Revert "jemalloc: Enforce alignment-must-divide-size rule of aligned_alloc."

Apparently this restriction was lifted in C17, and this was even
documented in a part of the man page I didn't notice because I got
stuck at the incomplete sentence `The aligned_alloc function conforms
to.'.  Sorry for the noise, folks.
