Skip incompatible QTextLayout tests when dpi-scaling is used
On e.g. Android, the tabs will be scaled by DPI. This breaks the
logic in the QTextLayout tests for tabs. It's not possible to
just scale the expected sizes either, since the whole text layout
will be affected by font sizes and scaling, and it's difficult to
predict where characters will land on different platforms and
resolutions.
To avoid breaking this test on other platforms, we just skip them
when we know they will break. Since the code tested is
cross-platform, this will hopefully not have any significant
impact on our coverage.
