QtMultimedia plugins are not deployed to Android .apks

QtMultimedia has two plugins:

> pwd
/Users/ollivuolteenaho/Qt/6.7.0/android_arm64_v8a/plugins/multimedia
> ls
libplugins_multimedia_androidmediaplugin_arm64-v8a.so
libplugins_multimedia_ffmpegmediaplugin_arm64-v8a.so

These are supposed to be deployed to Android APKs by androiddeployqt, but with the latest changes they are not being included and as a result:

I QtCore  : Start
I Qt      : qt started
E QtLoader: Can't find '/data/app/~~BP-2NNvZm4m2IVkZ1rYkog==/org.qtproject.example.appbug_ffmpeg-0J2lpIOQwlGkF0Giukamxw==/lib/arm64/libplugins_multimedia_ffmpegmediaplugin_arm64-v8a.so'
E QtLoader: Loading Qt native libraries failed 

Minimal reproducable example included (it's just a QtC Qt Quick default template with import QtMultimedia added to Main.qml). You need Qt 6.7 beta 3 with Android and Qt Multimedia components, and an Android device or emulator to deploy to. Make, build, deploy -> should fail.

semlanik, I'm guessing this is related to https://codereview.qt-project.org/c/qt/qtbase/+/530186?
