tty: do not close /dev/tty on macos

Browse source 
Attempting to close /dev/tty may block indefinitely on macos if another
thread is already blocked on a read operation. As there is no practical
use for closing /dev/tty on exit besides unblocking other threads (which
does not work on macos anyway) we can just skip the close call.
