lsfd: fix const qualifier warning in strnrstr

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

The function returns a non-const pointer into the haystack parameter,
and callers modify the string through that pointer. Therefore, the
haystack parameter should be char * rather than const char *.
