[scudo][standalone] Reduce Android region sizes to 128MB

Summary:
Unity is making irresponsible assumptions as to how clumped up memory
should be. With larger regions, we break those, resulting in errors
like:

"Using memoryadresses from more that 16GB of memory"

This is unfortunately one of those situations where we have to bend to
existing code because we doubt it's going to change any time soon.

128MB should be enough, but we could be flirting with OOMs in the
higher class sizes.
