kbuild: Enable -Wuninitialized
This helps fine very dodgy behavior through both -Wuninitialized (warning that a variable is always uninitialized) and -Wsometimes-uninitialized (warning that a variable is sometimes uninitialized, like GCC's -Wmaybe-uninitialized). These warnings catch things that GCC doesn't such as: https://lore.kernel.org/lkml/86649ee4-9794-77a3-502c-f4cd10019c36@lca.pw/ We very much want to catch these so turn this warning on so that CI is aware of it.
