insync Qt dependencies

>>> package: dev-qt/qtmultimedia-5.15.14
 *  - /usr/lib64/libQt5Multimedia.so.5
 *  - /usr/lib64/libQt5Multimedia.so.5.15.14
 *      used by /opt/insync/PySide2/Qt/qml/QtMultimedia/libdeclarative_multimedia.so (net-misc/insync-3.9.4.60020-r2)

I think we're missing a dep here on dev-qt/qtmultimedia:5, but when looking I noticed there's no SLOT specifiers for any of the Qt dependencies.

We need to also ensure we get to block Qt removal from the tree.

I am actually not so sure about all the PySide2 stuff. I guess like 90% of it is not needed as they might only use 1 or 2 libs from it, which is why it's bundled.

I'm also not a fan of "hard wiring" Qt5 here, as it is about to be phased out.

I've added /opt/insync/PySide2/Qt/qml/QtMultimedia/libdeclarative_multimedia.so to the big block of removals as it doesn't seem to be used.

Thanks. Was going to look into it in more depth today, so thanks for taking care of it. Let's close this then. I'll let you know if there's more that can be cleared out then.
