Fix CppunitTest_chart2_xshape failing with Display Scaling on Windows

See thread starting at
https://lists.freedesktop.org/archives/libreoffice/2018-December/081589.html

Regression from commit 7263d223ddf42cc39d10a501159c7b04ef48df96.
That change has made unit tests DPI-aware; and then some tests started
failing on systems with resolutions other than 96 DPI.
It has been suggested that the proper fix would be to do for Windows
what commit ada20402efa81273e03e46cbedc21f25b9daeeac did for macOS.
Another approach would be to fix all the tests to be DPI-aware.
I cannot do the first mentioned fix; so I have fixed testFDO74215 test
in sw_ooxmlexport4; and added DPI checks to the other failing tests in
chart2_xshape and sc_subsequent_filters_test to skip testing when using
non-default DPI. This is not ideal, of course, and conditionally skipped
tests need to be re-enabled unconditionally once a proper fix arrives.
