We want to reopen the console used for logging when running as PID1, but also when running a user manager (c.f.48a601fe5dand2a646b1d62). But this can cause problems when the binary is invoked directly, e.g. to print --help. E.g. if we ignore SIGPIPE, we'd remain running briefly after '/usr/lib/systemd/systemd --help | head -n1'. Previusly, the getopt machinery would print to stderr unconditionally. But after the rework of option parsing, which means that we use the log_* functions to repor errors, the test that checks if we print errors to stderr started failing. So let's skip some more of the setup if !invoked_by_systemd().
