qt5base: add Config.in option to pass custom Qt5 options

To reduce the qt5base binary size, we can disable unnecessary features.
Instead of trying to map every qt5base option to buildroot, create a
single config that we can pass any option too. Then append those to the
ones generated by buildroot.
