Handle upstream events when select-all is set

When used with clutter-gst sink or with ximagesink, camerabin posts the
warning: "Internal GStreamer error: clock problem.". 

Aditional debug info: "gstbin.c(2375): gst_bin_do_latency_func ():
/GstCameraBin:camerabin: Failed to configure latency of 0:00:00.000000000"

This is because input-selector doesn't handle upstream events when select-all
is set. The warning doesn't occur with xvimagesink because this sink doesn't
forward the latency event upstream, so it never reaches input-selector.

This patch forwards the event to all sink-pads when select-all is set. It
succeeds if any of the pads does, because when select-all is set the pads that
are connected to input-selector sink pads might not be active and not handle
the event. This affects only the input-selector copy in camerabin.
