suppress early syslog return when log socket cannot be opened

this behavior is no longer valid in general, and was never necessary.
if the LOG_PERROR option is set, output to stderr could still succeed.
also, when the LOG_CONS option is added, it will need syslog to
proceed even if opening the log socket fails.
