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/[email protected]/
We very much want to catch these so turn this warning on so that CI is
aware of it.
