This commit introduce a new sink: syslog_sink. This sink is Linux only, and will write log entries to the system logger, using the syslog() library call. It is instanciable using spdlog::syslog_logger(name). Note that the suffix _st or _mt is not present, as syslog() is thread-safe. I also applied @gabime reviews and added license header.
