Add a helper to check if the filesystem supports sparse files. This is used to guard tests that exercise sparse file functionality and would take forever on filesystems that have to zero all blocks on extending truncates. Unfortunately there's no good way to autodetect this functionality, so just implement it as a blacklist for now.
