shared: Fix to release channel resources when sensor_listener is released

In the event loop object, channel resources(class 'channel' and
'channel_handler') to be released are added to the queues through
functions: add_channel_release_queue, add_channel_handler_release_list
respectively.

Resources contained by these queues should be freed by function
g_io_handler but this function is called when channel receives a
event(GLib.IOCondition) and if no event is occured, resources are not
released. This may cause resources like socket fd, memory flooded, so
they should be released

To resolve this issue, a function is added to the event_loop class to
release resources contained by the queues and that function is called by
the sensor_listener when it is released.
