package/qt5/qt5base: add BR2_PACKAGE_QT5BASE_OPENSSL

Commit c110e48cecde6f543da18388322907b05b25e7d2 disabled openssl support
on QT 5.6, this has the side-effect of breaking the build of
python-pyqt5 because support of openssl is enabled on python-pyqt5 if
BR2_PACKAGE_OPENSSL is selected

To fix this issue, add a new BR2_PACKAGE_QT5BASE_OPENSSL option in
qt5base and use it in python-pyqt5
