input-selector: Remove obsolete 'block' signal

Browse source 
This signal blocks the input-selector with no means of unblocking
other than a state change back to READY. It seems this signal was
part of an old way of synchronously switching the selector,
together with the already-removed 'switch' signal.

Removing the signal is safe, as attempting to use it could only
end in deadlocks. Attempting to emit an unknown signal just causes
g_criticals.
