scripts: Reduced table name widths to 8 chars minimum

I still think the 24 (23+1) char minimum is a good default for 2 column
output such as help text, especially if you don't have automatic width
detection. But our result scripts need to be a bit more flexible.

Consider:

  $ make summary
                              code     data    stack  structs
  TOTAL                      68864        0     3744     1520

Vs:

  $ make summary
              code     data    stack  structs
  TOTAL      68864        0     3744     1520

Up until now we were just kind of working around this with cut -c 25- in
our Makefile, but now that our result scripts automatically scale the
table widths, they should really just default to whatever is the most
useful.
