Reduce the namei (sub)display by 5 columns to make enough space for a

new vnstat display to the right of the namei display.

Move the non-vmstat fields {des,num,fre}vn from the vmstat display to a
new vnstat display.  Move the dtbuf field there too.  The buf and dtbuf
fields are non-vmstat and non-vnstat, so there is no good place to
display them.  I need to move at least 1 of them out of the vm stats
for further cleanups of the vm stats, and there is only space for 1
of them in the vn stats.  (The best place for the current buf field
is actually /dev/null, since it has been completely broken for about
10 years and broken for longer.  It gives an uninteresting virtual
memory count where an interesting real memory count is wanted.)
