tools/headers: Pull in stddef.h to uapi to fix BPF selftests build in CI
With recent sync of linux/in.h tools/include headers are now relying on
__DECLARE_FLEX_ARRAY macro, which isn't itself defined inside
tools/include headers anywhere and is instead assumed to be present in
system-wide UAPI header. This breaks isolated environments that don't
have kernel UAPI headers installed system-wide, like BPF CI ([0]).
To fix this, bring in include/uapi/linux/stddef.h into tools/include.
We can't just copy/paste it, though, it has to be processed with
scripts/headers_install.sh, which has a dependency on scripts/unifdef.
So the full command to (re-)generate stddef.h for inclusion into
tools/include directory is:
$ make scripts_unifdef && \
cp $KBUILD_OUTPUT/scripts/unifdef scripts/ && \
scripts/headers_install.sh include/uapi/linux/stddef.h tools/include/uapi/linux/stddef.h
This assumes KBUILD_OUTPUT envvar is set and used for out-of-tree builds.
