.macos: Set keyboard repeat rate on macOS Sierra

Unfortunately it seems the float trick (6b4d9617a059e3ece468e3a9150ea920cadb1fe2) no longer works in macOS Sierra. As @kirbysayshi pointed out, setting `KeyRepeat` to a float or zero value actually *disables* key repeat now (i.e. holding a key does nothing). It seems like setting it to `1` is the best we can do for now. Note that this is way slower than before.

Ref. #687.
