[wpilibj] DataLogManager: Fix behavior when low on space (#6486)

Browse Source 
Uses getUsableSpace in Java, matching how C++ determines available space (C++ calls it available, but they mean the same thing.) This fixes a bug where logs wouldn't get deleted due to incorrect available space detection.

The DataLog thread now also checks if the state was marked as stopped after a call to StartLogFile.
