kbuild: remove redundant extra warning flags
There is no point in turning individual options off and then on again, or vice versa, as the last one always wins. Now that -Wextra always gets passed first, remove all the redundant lines about warnings that are implied by either -Wall or -Wextra, and keep only the last one that disables it in some configurations. This should not have any effect but keep the Makefile more readable and the command line shorter.
