bnc#812796: Correctly handle static value array for OOXML charts.

We need to pass the role of the data sequence in order to avoid unreliable
guess work when importing static value array.

Also, not all Excel's scatter plots have real numeric X values; some have
textural X values in which case Excel switch to generating 1, 2, 3, ... as
X values.  When importing to our chart implementation, using "categories" role
in such cases instead of "values-x" results in a more faithful chart rendering.
