[scudo] Change the default MinReleaseToOsIntervalMs to -1
The page releasing has been greatly improved and the memory grouping
avoids growing memory footprint too fast. Besides, every release
interval change will introduce a M_PURGE call which ensure the memory
usage won't be impacted by the different release interval. It's safe to
release the interval constraint.
Test: builds
