add process name and pid in syslog message sent by RemoteSysLog

RemoteSysLog is usefull when real syslog is not available. As explained in
rfc3164 (§5.3) we should provide process information as process name and pid.
This make filtering message much more easy.
Indent all policy code according to style guide.
