worked around Falcon.app agent slowing everything down, fixes #492

it appears the Falcon anti-malware product for end-points slows down ps -t /dev/ttysXXX
commands 🤷

the workaround consists in passing ttysXXX instead of /dev/ttysXXX and is achieved
by removing the /dev/ prefix in #{pane_tty} expansion with the help of formats
substitutions
