- BR hicolor-icon-theme for directory ownership

- Added pass-in-freetype2.patch:
We also need to check for HarfBuzz as the internal drawing code
also loads HarfBuzz header files.
The finder is a copy of the same file already in the freetype
intree copy.

- update patch with the changes from the pull request
- enable internal drawing code again

- disable internal drawing code because it requires an msdfgen.h

- add BR for glibc locale package and set UTF-8 locales as the
tooling complains about non UTF-8 locales

- added no-libraries-from-internet.patch:
use patch proposed in
https://github.com/musescore/MuseScore/issues/24235#issuecomment-2313896167

- enable use of system libraries for tinyxml2 and opus(enc)

- switch to Qt6
- drop use-qtmake-qt5.patch as Qt5 is no longer used
