Subject: [PATCH] Include config.hpp before checking BOOST_LOG_WITHOUT_SYSLOG.

Boost.Log's config.hpp may define BOOST_LOG_WITHOUT_SYSLOG if no native
syslog API or Boost.ASIO is available, so we need to include the header
before checking the macro.

Closes https://github.com/boostorg/log/pull/123.
