[Devel] [PATCH vz10 2/2] selftests/tcp_ao: Fix -Wdiscarded-qualifiers under C23

[Eva Kurchatova]

glibc ≥ 2.42 (GCC 15) defaults to -std=gnu23, which promotes
-Wdiscarded-qualifiers to an error.

In C23, strstr() and strchr() return "const char *".

Change variable types to const char * where the pointers are never
modified (column)

Feature: fix ms/selftest
