add process name and pid in syslog message sent by RemoteSysLog

rfc3164 (§5.3) we should provide process information as process name and pid.
This make filtering message much more easy.

Fix uptime matching pcre_compile call and reset errno.

pcre_compile requires errptr to be present, and we should not tie the

Additionally, reset errno before we try to call any uptime functions,
since otherwise we may get an error message even when there is no
error.
