Fix problems when HAMLIB_KEYER is set, but rig control is disabled

When HAMLIB_KEYER is set, but rig control and keying is disabled via
`tlf -r`, hitting ESC will trip the assert(init_called) in
rig_has_stop_morse.

Protect the hamlib_keyer_* functions against being called in that mode.

In passing, decrease the timeout after showing the "keying disabled"
message to 1s.
