[OE-core] [PATCH] kernel.bbclass: fix some incorrect inter-task dependencies

[liu.ming50 at gmail.com]

From: Ming Liu <peter.x.liu at external.atlascopco.com>

- Move the addtask statment that kernel_link_images needs run after
  do_compile from linux-yocto.inc to kernel.bbclass. Or else the recipes
  that inheriting kernel.bbclass might run into implicit dependency
  issues.
- Fix a typo, "addtask do_strip" should be "addtask strip".
- Remove some redundant addtask statments, when "addtask A after B" is
  set, then "addtask B before A" is not needed.
