shared,generic: move tests using duperemove to generic/

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
