Revert "toolchain: fortify-headers: Fix build of some packages"

This reverts commit 61f16a6960.

The new fortify-headers version needs some more work to be usable in
OpenWrt. Revert this to fix the builds again.

-Subject: Check if FORTIFY_USE_NATIVE_CHK is defined
-
-The previews code tried to get the value defined for
-FORTIFY_USE_NATIVE_CHK and this resulted in some build errors like
-this:
-```
-/include/fortify/stdio.h: In function 'vsnprintf':
-/include/fortify/stdio.h:155:49: error: "FORTIFY_USE_NATIVE_CHK" is not defined, evaluates to 0 [-Werror=undef]
-  155 | #if __has_builtin(__builtin___vsnprintf_chk) && FORTIFY_USE_NATIVE_CHK
-      |                                                 ^~~~~~~~~~~~~~~~~~~~~~
-```
-
-Check if it is defined instead.
