Investigate what patching operations are still needed for Qt framework

We do patching of Qt binaries in multiple phases:

• Build time (e.g. relative RPaths)
• Build artifact export (pre-patching)
• Packaging (e.g. RPaths, build time paths, Android specific items, ..)
• Installation phase (qmake -query output usage, otool, .., files-to-patch resource files)

It may be that part of the patching is in place due to historic reasons (Qt5). This should be analyzed what patching is needed anymore. We might be doing unnecessary steps.
