Miroslav Lichvar 7b98443a13 logging: don't write fatal messages to invalid descriptor ...

If opening the log file specified with the -l option failed (after
closing all descriptors), the error message is written to an invalid
descriptor as no log file or syslog is opened yet. Fix the code to track
when the output is usable.
