[scudo] Let allocator config limit the page releasing interval

On Android, this interval constraint was used to avoid increasing the
memory pressure by a long interval. Now the memory footprint is managed
better and we always do a M_PURGE call before changing the interval.
It's better to remove this legacy constraint.
