Only retain for 64 bit.android11-dev
In 32 bit, the va space can be exhausted very easily. Change the
jemalloc defaults to only retain for 64 bit to avoid this exhaustion.
The performance of traces does get slightly worse, but most stay about
the same.
This should only affect devices that use malloc svelte, all other
devices are on scudo.
