[Bug]: 6.8.1 installations fail, improper archive unpacking

[tsteven4]

Bug description

In 6.8.1 Updates.xml files PackageUpdate elements can contain an Operations element. These can contain Operation elements with attribute Extract, which in turn contain Argument elements that contain the target directory for extraction as well as the name of the 7z file.

For example see https://download.qt.io/online/qtsdkrepository/linux_x64/desktop/qt6_681/qt6_681/Updates.xml

aqtinstall doesn't handle these optional elements, instead unpacking everything assuming the path names are stored in the 7z file. This is no longer true for 7z archives in 6.8.1.

aqt install-qt linux desktop 6.8.1 linux_gcc_64 -O /tmp/Qt -m qt3d qt5compat qtconnectivity qtimageformats qtlanguageserver qtlocation qtmultimedia qtpdf qtpositioning qtquickeffectmaker qtremoteobjects qtscxml qtsensors qtserialbus qtserialport qtspeech qtwebchannel qtwebengine qtwebsockets qtwebview
leads to
ERROR : Updater caused an IO error: [Errno 2] No such file or directory: '/tmp/Qt/6.8.1/gcc_64/mkspecs/qconfig.pri'
This would seem to be caused by unpacking all archives in the wrong place. All 7z archives are unpacked to the directory supplied in the command line, missing at a minimum the usual version/compiler/ path component, in this case we would have expected everything to go to /tmp/Qt/6.8.1/gcc_64/. Thee missing pathname components appear to all be given in Argument elements. Note these missing pathname components may contain additional subdirectories besides the version/compiler components, for example icu-linux-Rhel8.6-x86_64.7z should have been unpacked to @TargetDir@/6.8.1/gcc_64/lib.

$ ls /tmp/Qt
bin      lib               libicudata.so.73.2  libicuio.so.73    libicutest.so.73.2  libicuuc.so.73    mkspecs      plugins    sbom

include  libicudata.so.73  libicui18n.so.73.2  libicutest.so.73  libicutu.so.73.2    metatypes         phrasebooks  resources

Note I was testing with code from #838 but this should be reproducible with released code if one omits the modules qtwebengine and qtpdf which are extensions in 6.8 (#803).

Expected behavior

A correct directory structure, in the example in /tmp/Qt/6.8.1/gcc_64.

In case it helps anyone, these changes worked for me. I'm not confident with the code quality as I'm mostly unfamiliar with Python and some of it is AI-generated, but it at least seems to function okay.

I would like to merge #841 and then try to merge another PRs
