Convert handles of built-in shapes in Impress when exporting to PPTX.

For those shapes exported as OOXML preset shapes, their AdjustmentValues
property was exported as the list of adjustment values ( avLst )
in the exported PPTX file. This works for shapes imported from
PPTX, whose AdjustmentValues is exactly the same as avLst of the
original PPTX file.

For built-in shapes in Impress, avLst and AdjustmentValues would not
be the same because the path and the equation created by LibreOffice
and OOXML are not the same.

This patch convert position of handles to adjustment values according to
the shape type case by case. It also adds default values if the built-in
shape in Impress has fewer handles then the exported preset shape because
Powerpoint seems to be very strict about the number of values in avLst,
and deemed the file as corrupted if any of defined adjustment values is
missing.

Round-rectangular-callouts, rectangular-callout, and round-callouts
are added to the blacklist so that they are exported as preset shapes.
