Subject: [PATCH] Only move XAUTHORITY if it's temporary
References: boo#1084798

If kdeinit is started within a session spawned by kdesu or similiar, it has
a temporary file as $XAUTHORITY. As kdeinit is persistent, the used .Xauthority
file must persist as well otherwise launched child process would have no access
to X. kdeinit works around the file's volatileness by copying it to a known
location. Unfortunately the chosen location (/tmp) gets cleared regularly which
means it's even more volatile than the source...

Even more unfortunately, this workaround is applied WAY to broad. Even when
$XAUTHORITY points to a static file, like in a normal user session, it moves
.Xauthority around.

Work around this issue by only applying it if $XAUTHORITY is in /tmp, where
kdesu places it.
