Some applications might activate -Werror=format-nonliteral when building
their application. This breaks fortify headers build. Tell GCC to ignore
such warnings for this code.
This fixes the libubox and ucode build:
```
/include/fortify/stdio.h: In function 'snprintf':
/include/fortify/stdio.h:101:9: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]
101 | return __orig_snprintf(__s, __n, __f, __builtin_va_arg_pack());
| ^~~~~~
/include/fortify/stdio.h: In function 'sprintf':
/include/fortify/stdio.h:110:17: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]
110 | __r = __orig_snprintf(__s, __b, __f, __builtin_va_arg_pack());
| ^~~
/include/fortify/stdio.h:114:17: error: format not a string literal, argument types not checked [-Werror=format-nonliteral]
114 | __r = __orig_sprintf(__s, __f, __builtin_va_arg_pack());
| ^~~
cc1: all warnings being treated as errors
ninja: build stopped: subcommand failed.

This reverts commit 6268692bd2.
The new fortify-headers version needs some more work to be usable in
OpenWrt. Revert this to fix the builds again.

Fix some warnings and compile errors generated by the new
fortify-headers when compiling some applications like strace.

Add the __extension__ mark before #include_next in strings.h
to avoid a compiler error when -pedantic is enabled.
This has been done for all other headers in the past.
