tmux: Undo TERM hacking

Undoes the hack introduced in 1136ef2
to fix the combination of Home/End keys, italics in Vim, and background
highlighting in Delta.

This works on my Fedora system at home, so I need to go test on my
Ubuntu 22.04 system at work - suspect that the tmux-256color termcap has
been fixed on at least Fedora.

Fixes #143
