[libFuzzer] in dfsan mode, set labels every time we start recording traces as opposed to doing it at process startup. This ensures that the labels are fresh.

[lib/Fuzzer] start getting rid of std::cerr. Sadly, these parts of C++ library used in libFuzzer badly interract with the same code used in the target function and also with dfsan. It's easier to just not use std::cerr than to defeat these issues.
