[Bug 2154343] Re: ubuntu_bpf: FTBFS with clang 23 / gcc 15

This bug is awaiting verification that the linux-nvidia/7.0.0-1016.16 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-resolute-linux-nvidia' to 'verification-done- resolute-linux-nvidia'. If the problem still exists, change the tag 'verification-needed-resolute-linux-nvidia' to 'verification-failed- resolute-linux-nvidia'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Since `prog_name[i]` is a `const char *`, the returned pointer should also be treated as const-qualified. Update `tgt_name` to `const char *` to match the type of the underlying string and silence the compiler warning. ``` [How to reproduce] Run test again after applying the patch [Regression potential] Low: clean upstream cherry-pick for a known issue.
