[Buildroot] [RESEND v3 0/1] support: kconfig: Fix compiler warnings

[Kanak Shilledar]

Hi,
While building the `master` branch on Ubuntu 24.04.4 I am getting the
warning of `-Wformat-overflow=`.

```
./util.c: In function ‘file_write_dep’:
./util.c:86:26: warning: ‘%s’ directive writing 10 or more bytes into a region of size between 1 and 4097 [-Wformat-overflow=]
   86 |         sprintf(buf2, "%s%s", dir, name);
      |                          ^~
./util.c:86:9: note: ‘sprintf’ output 11 or more bytes (assuming 4107) into a destination of size 4097
   86 |         sprintf(buf2, "%s%s", dir, name);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```

I tried this on the release `2026.02.x` and this warning exists there as
well. I am running GCC version `(Ubuntu 13.3.0-6ubuntu2~24.04.1) 13.3.0`

Thanks and Regards,
