Bugfix: do not count tmux source-file as tmux process
Do not count `tmux source-file .tmux.conf` as a tmux process when checking if
other tmux server is running.

Previously, this caused interpolation command not to be inserted into
`status-right` because `tmux source-file` was falsely detected as another tmux
server.
