Add xterm+pcfkeys to tmux

[Nicholas Marriott]

Hi

>From the next release (around May) tmux will generate xterm-style escape
sequences for function keys out of the box (the xterm-keys option will
initially default to on and later be removed).

So if would be great if xterm+pcfkeys could be added to the tmux
entry. Below is a diff against terminfo-20161126.src.

Currently we generate nothing for these keys by default so this
shouldn't make any difference even for older tmux versions.

Thanks
