Fix flakiness in tst_QGlyphRun::drawRightToLeft

As described in 3279c8e7d72c5eee379fa8e4a2789acfe40445c0, we can't
depend on the widths of decoration to always be the same for
drawText() and equivalent drawStaticText/drawGlyphRun.

This is typically visible as an off-by-one when using the default
fonts on OpenSUSE.

Since this test was actually made to test positions of RTL glyphs,
we can just disable the decoration and simplify the text.

Fixes: QTBUG-89086
