Subject: [PATCH iproute2] configure: Remove include <sys/stat.h>

The check_name_to_handle_at() function in the configure script is
including sys/stat.h. This include fails with glibc 2.36 like this:
````

Just removing the include works, the manpage of name_to_handle_at() says
only fcntl.h is needed.
