Update jemalloc to 4.1.0.
Add missing Symbol.map entry for __aligned_alloc.
Add weak-->strong symbol binding for
{malloc_stats_print,mallctl,mallctlnametomib,mallctlbymib} -->
{malloc_stats_print,mallctl,mallctlnametomib,mallctlbymib}. These
bindings complete the set necessary to allow applications to replace all
malloc-related symbols.
