add configuration for self-init
...
This needs to be disabled for compatibility with the exploit protection
compatibility mode on GrapheneOS. hardened_malloc shouldn't be trying to
initialize itself when exploit protection compatibility mode is enabled.
This has to be handled in our Bionic integration instead.

treat zero size malloc as unlikely
...
Calls to malloc with a zero size are extremely rare relative to normal
usage of the API. It's generally only done by inefficient C code with
open coded dynamic array implementations where they aren't handling zero
size as a special case for their usage of malloc/realloc. Efficient code
wouldn't be making these allocations. It doesn't make sense to optimize
for the performance of rare edge cases caused by inefficient code.
