input: kitty: printables are emitted as text, even if Caps- or Num-Lock is in effect

Browse source 
Not sure if this is the best/correct way to do it. But kitty seems to
ignore at least Num-Lock for printables, while it _does_ affect other
keys. For example, Return, which usually emits ‘\r’, are affected by
Num-Lock and emit ‘CSI 13;129u’.

Note that as soon as some other modifier is in effect, the Num-Lock
modifier *is* encoded in the CSI, also for printables.
