mktables: Calculate debugging information placement

mktables: Calculate debugging information placement

When outputting debugging information under the -annotate option, it's
nice to line up the columns.  This commit does a pass through the tables
where the final real data column is variable width so that it can figure
out where to put the debugging info so as almost all of the columns can
be lined up, and not have to be right-shifted because of overlong real
data.

Certain tables prior to this commit had been manually eyeballed and
column information hard-coded in.  This is no longer necessary.  This
means that one parameter to the write() function is no longer used, and
is removed here.
