package/python-pyqt5: fix QtLocation module dependency

The QT module location from qt5location depends on
QT quick from qt5declarative.

>From qt5location-5.14.2/src/src.pro:

  qtHaveModule(quick) {
      SUBDIRS += positioningquick location
      ...
  }

Adjust pyqt5 QtLocation module dependency accordingly.

Fixes:
