glibc ≥ 2.42 (GCC 15) defaults to -std=gnu23, which promotes -Wdiscarded-qualifiers to an error in the default hardening flags of Fedora Rawhide, Arch Linux, openSUSE Tumbleweed, Gentoo, etc. In C23, strstr() and strchr() return "const char *" in most cases, making implicit casts from const to non-const invalid. This breaks the build of tools/bpf/resolve_btfids on pristine upstream kernel when using GCC 15 + glibc 2.42+. Fix the three remaining instances with explicit casts. No functional changes.
