log: Fix qemu_set_log_filename() error handling
When qemu_set_log_filename() detects an invalid file name, it reports an error, closes the log file (if any), and starts logging to stderr (unless daemonized or nothing is being logged). This is wrong. Asking for an invalid log file on the command line should be fatal. Asking for one in the monitor should fail without messing up an existing logfile. Fix by converting qemu_set_log_filename() to Error. Pass it &error_fatal, except for hmp_logfile report errors. This also permits testing without a subprocess, so do that.
