namei: fix const qualifier warning in readlink_to_namei

Fix const qualifier discarded warning in readlink_to_namei().
This warning is reported by gcc 15 which defaults to the C23 standard.

The strrchr() function returns a pointer into a const string, so the
receiving variable must be declared as const char *.
