tsan: don't leave unmapped hole in non-app memory
If an app mmaps lots of memory, a user mmap may end up
in the tsan region for traces. Shadow for this range
overlaps with shadow for other user regions.
This causes havok: from false positives to crashes.
Don't leave unmapped holes in the traces region.
