scd: Remove --debug-disable-ticker option.

Browse Source 
* scd/scdaemon.c (ticker_disabled): Remove.
(handle_tick, need_tick): Remove.
(handle_connections): Don't check ticker_disabled.

--

Now, removal of device/card is only done by the function
scd_update_reader_status_file, it should be called if needed.

We poll every 500ms to let the user immediately know a status

For a card reader with an interrupt endpoint, this timer is not

This is not too good for power saving but given that there is no
easy way to block on card status changes it is the best we can do.
