Make `kitten transfer` work in tmux

Describe the bug Transferring files in a tmux session doesn't work for me, as the confirmation prompt to allow the transfer is never shown.

To Reproduce Steps to reproduce the behaviour:

Connect to machine with kitten ssh foo@example.com
Open a new tmux window with tmux
Run kitten transfer foo bar
Pane hangs forever with message Found 1 files and directories, requesting transfer permission…

Additional context Reproducible with kitten --config NONE. Haven't tried to reproduce it with a fresh environment and fresh tmux on the remote system yet. I would only go in that hustle if it's not reproducible by others.
