Replay key if kboard is interrupted while initializing (Bug#37782)

Browse source 
The problem with the original fix for bug#5095 is that it drops
the current event, which is a valid character event and not -2.
Thus, the first ESC character sent by the terminal after turning
on focus tracking is lost and we get '[' and 'I' events separately
inserted into the buffer afterwards.

* src/keyboard.c (read_key_sequence): Add key as mock_input and replay
sequence using new keyboard, when the key is not -2.
