testexport.bbclass: Split testimage class

This adds a new class that only export tests of images,
the code was taken from testimage class and most of it
wasn't modified. Just add some vars for the new class.

testexport class require testimage class to get the
test suites defined for all the images.

+# testexport.bbclass allows to execute runtime test outside OE environment.
+# Most of the tests are commands run on target image over ssh.
+# 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
+# - 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.
