xfstests: add _require_sparse_files

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.
