Array controls weren't skipped when only V4L2_CTRL_FLAG_NEXT_CTRL was provided (so no V4L2_CTRL_FLAG_NEXT_COMPOUND was set). This is wrong since arrays are also considered compound controls (i.e. with more than one value), and applications that do not know about arrays will not be able to handle such controls. Fix the test to include arrays.
