Deploy Tool "macdeployqt" on macOS puts QtVirtualKeyboard library in install bundle

When using:

~/Qt5.15.1/5.15.1/clang_64/bin/macdeployqt "$APPLICATION"

we noted that the library QtVirtualKeyboard (which is not covered by the open source license) is copied into software install directories we want to deploy. Even though it is not used at all in our source code.

The library can be found in ${APPLICATION}/Contents/Frameworks/QtVirtualKeyboard.framework. 

The only workaround seems to be to remove the library by hand. We find that our software is still working after that. (we only use open source parts of Qt!)

Note: on Windows we do not have the problem, since there is no deploy tool.

Please fix macdeployqt since it creates false library content information which can lead to misunderstanding with license violation.
