Revisit support for `-no-xinerama` associated with Qt 5.15.2

[jcfr]

As described in QTBUG-89364, specifying -no-xinerama does not work.

A patch have been provided in the referenced issue.

Since described tradeoff seems reasonable, we should consider applying the patch and avoid requiring the installation of additional packages like libxcb-xinerama0 as described in QTBUG-84749
