Avoid casting function pointer in libutil test support
...
Casting function pointers seems to be almost always UB.
See https://stackoverflow.com/questions/559581/casting-a-function-pointer-to-another-type
Fixed by doing the casting of `void*` to `std::string*` inside the function instead.
Caught by UBSan.

C API: Safer function pointer casting
...
See https://github.com/NixOS/nix/pull/8699#discussion_r1554312181
Casting a function pointer to `void*` is undefined behavior in the C
spec, since there are platforms with different sizes for these two kinds
of pointers. A safe alternative might be `void (*callback)()`
