#22096: Increase MALLOC_MP_LIM in sandbox.c

------------------------------+--------------------------------
See diagnosis at comment:15:ticket:21648 . Now that worker threads can
malloc a bit more, they can need to mprotect(...PROT_WRITE) larger chunks.
This requires an increase in MALLOC_MP_LIM.
In the longer term, we should replace our sandbox's string-interning hack
with a privileged helper hack.
