- Add QT5_CMAKE_OFF knob to ensure that right version is picked up if user
has both of them installed
- It no longer uses Shntool (not updated since 2009), so do not reference
it in pkg-message; instead, add `audio/opus-tools' which Flacon supports
since version 1.2.0
Because GitHub releases (tarballs) are not fetched with correct modification
