tdf#119908 sw smart justify: fix justification by shrinking

Shrink the exceeding lines by shrinking the spaces
between the words.

Because the negative spacing values are used
for the extra space between the characters in the main
data structure of the justified line layout, and not for
the space between the words, like the positive values,
the negative space values for shrinking are stored over
LONG_MAX/2 as absolute values to avoid of bigger changes
of the data structure before designing a better
justification algorithm, where it's possible to mix
different methods for the more visible text layout.

Note: the text cursor doesn't follow the new word
positions yet.

Follow-up to commit 7d08767b890e723cd502b1c61d250924f695eb98
"tdf#130088 tdf#119908 smart justify: fix DOCX line count + compat opt."
