classes/testexport: move to classes-recipe

This class should be in classes-recipe as, like testimage, it is specific
to image recipes.

This also solves a regression where simply IMAGE_CLASSES += "testexport"
doesn't work if testimage isn't already in IMAGE_CLASSES. The testexport
class adds testimage to IMAGE_CLASSES, but by this point it's too late.
Now that the class can only be inherited via IMAGE_CLASSES, we can
simply inherit testimage directly.

 # To use it add testexport to global inherit and call your target image with -c testexport
 # You can try it out like this:
 # - First build an image. i.e. core-image-sato
-# - Add INHERIT += "testexport" in local.conf
+# - Add IMAGE_CLASSES += "testexport" in local.conf
 # - Then bitbake core-image-sato -c testexport. That will generate the directory structure
 #   to execute the runtime tests using runexported.py.
 #
 # For more information on TEST_SUITES check testimage class.
