change set_return_on_destroy tool to take a fshandle

dmapi/src/common/cmd/set_return_on_destroy.c

@@ -40,13 +40,15 @@
 Test program used to test the DMAPI function dm_set_return_on_destroy().  The
 command line is:
 
-	set_return_on_destroy [-s sid] pathname [attr]
+	set_return_on_destroy [-F] [-s sid] {pathname|fshandle} [attr]
 
 where pathname is the name of a file which resides in the filesystem of
 interest.  attr is the name of the DMAPI attribute; if none is specified,
 then set-return-on-destroy will be disabled for the filesystem.
 sid is the session ID whose attribute you are interested in setting.
 
+Use -F if you want the program to find the fshandle based on the pathname.
