Add _require_scratch_duperemove which validates that the file system supports duperemove. This allows us to move three tests from shared/ to generic/. This means these tests will automatically adapt when duperemove supports other file systems. Tests moved are: shared/008 --> generic/559 shared/009 --> generic/560 shared/010 --> generic/561 Signed-off-by: Theodore Ts'o <tytso@mit.edu> Reviewed-by: Eryu Guan <guaneryu@gmail.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
