vt: fix home/end sequences in xterm mode

According to the ncurses terminfo database, we have

$ for k in khome kend; do printf '%s:\t' "$k"; TERM=xterm tput $k | od -An -tc; done
khome:	033   O   H
kend:	033   O   F
$

This differs from vt220fk, so add a new xtermfk table with the proper
sequences.
