zoom: force use of system QT6 to fix missing libQt6Bodymovin.so

Testing the changes

• I tested the changes in this PR: YES

Closes #60526

libQt6Bodymovin.so was required by the non-systemqt build of zoom. This seems to be a new dependency not present in previous versions.

Unfortunately because Zoom 7.0.0 doesn’t ship libQt6Bodymovin.so, therefor the new Zoom version was broken with the most recent qt6-lottie.

This PR removes the systemqt option and forces Zoom to use the system’s Qt6. I don’t think there is much value in using Zoom’s own Qt6 libraries anyway. It also removes the outdated rm -rf ... calls, since most of these files are not in the Zoom 7.0.0 RPM.

None of these invocations of rm should use the -f flag. It masks changes to file structures that should be made obvious by a failure to build.

Thank-you for the review.

I cannot find the missing libQt6Bodymovin.so in our system qt6 either?

xlocate libQt6Bodymovin.so

returns no result

zoom seems to ship only half of qt6 libraries its using. They ship libQt6Lottie.so which links libQt6Bodymovin.so, but don't ship that file. And the system version of qt6 is newer and doesn't provide that file either, but also doesn't link it.
