Subject: Fixed hiding mouse cursor (Thanks to Roland Scheidegger)

The cursor never disappears because there seem to be incoming
xshm completion events every frame (for these events to arrive it is not
necessary to actually have xshm support compiled into vdr-sxfe), so
there's never a poll timeout and as a consequence the mousecursor
timeout never expires.
