Format security error in dbeacon.cpp

dbeacon.cpp: In function 'void d_logv(int, const char*, __va_list_tag*)':
dbeacon.cpp:250:23: error: format not a string literal and no format arguments [-Werror=format-security]
   syslog(level, buffer);

Need to fix this to satisfy Debian hardening requirements.
