Conan: Do not force 'qt_host_path' usage in cross-build context

If the user does not pass:

  -o qtbase:qt_host_path=/foo

then log a warning but allow to continue. For example Boot2Qt
integration resolves the 'QT_HOST_PATH' by other means thus making it
a mandatory option to be passed by the user should not be needed.

Pick-to: 6.3 6.4
