Iproute2 build generates a warning when built with gcc-12.
This is because the alg_key in xfrm.h API has zero size
array element instead of flexible array.
CC xfrm_state.o
In function ‘xfrm_algo_parse’,
inlined from ‘xfrm_state_modify.constprop’ at xfrm_state.c:573:5:
xfrm_state.c:162:32: warning: writing 1 byte into a region of size 0 [-Wstringop-overflow=]
162 | buf[j] = val;
| ~~~~~~~^~~~~
This patch convert the alg_key into flexible array member.
There are other zero size arrays here that should be converted as
well.
This patch is RFC only since it is only compile tested and
passes trivial iproute2 tests.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
