Sort tmux sessions by age
tmux has particular syntax for formatting internal state.
See tmux(1), /^FORMATS/.
This commit leverages the `tmux ls` subcommand, the tmux internal
`session_created` datetime variable, and the sort command to provide a
_tmux() statusline of sorted tmux sessions from oldest to youngest.
_sshd() and _tmux() are both improved with the usage of awk's `printf`
command instead of the `ORS` variable.
