Add tests for android qt 6.4.1, using "wrong" platforms

Since Qt 6.4.1, the Qt devs stopped building android binaries for
all platforms: see https://bugreports.qt.io/browse/QTBUG-108707

> we are building android packages only in one host & use those in other ones:
> android armv7 is build only in windows
> android arm64 is build only in mac
> android x86 and android x86_64 are build only in linux

This adds tests for Qt 6.4.1 on platforms that are not the platforms that
Qt was built for, so that:
* the binaries built on Mac are tested on Linux
* the binaries built on Linux are tested on Windows
* the binaries built on Windows are tested on Mac

There should be 3 more permutations of this pattern, but I prefer to
ignore them to save on CI build times.
