Subject: [PATCH] Notify systemd synchronously (bsc#1053376)

Forking the systemd-notify command is known to be unreliable at least
with older versions of the kernel and/or systemd. When systemd receives
the notification the systemd-notify process may have already exited
causing an error in the logs while waiting for a (90 seconds) timeout.

This patch instead notifies the systemd NOTIFY_SOCKET synchronously in
case the systemd.daemon python library is not available.

Fallback to systemd_notify_call() in case of socket.error
