wt-status: i18n of section labels

The original code assumes that:

(1) the number of bytes written is the width of a string, so they
can line up;

(2) the "how" string is always <= 19 bytes.

Neither of which we should assume.

Using the same approach as the earlier 3651e45c (wt-status: take the
alignment burden off translators, 2013-11-05), compute the necessary
column width to hold the longest label and use that for alignment.
