siproxd: improve syslog messages

Use explicit ident string ("siproxd") instead of NULL, as the latter is
not guaranteed to prepend the program name (e.g. unspecified in POSIX),
and may result in syslog messages identified only by PID.

Use consistent facility (LOG_DAEMON) across openlog() and syslog() calls.
