tdf#135184 add linecaps in charts

Chart is currently not able to interpret property linecap. But in
case of linecap 'round' or 'square', line dashes lengths are adapted
so that they look same as in MS Office (tdf#134053). This does not
work, if the corresponding linecap property is not interpreted.
Dashed border of data labels is not fixed because of bug
tdf#135366.
In addition I have fixed errors in prstDash detection, which I
have noticed while creating unit tests.
The unit tests cover file text, not visual appearence.
