CMakeLists: Add option to call lupdate directly

qt_create_translation silently fails to run at all on my system. Since
there is no error, I was unable to determine a fix. This sidesteps the
convenience function by setting up the rules ourselves.

This is left as an option since this path likely does not work on
Windows.
