lxqt: use modified LXQtConfigVars CMake macro

LXQt uses the values in this macro to set installation
directories and in the case of lxqt-session to substitute in paths.
However, by doing this all the paths are from within lxqt-build-tools
prefix. By utilizing a setup hook we can set the directories with the
correct prefix as cmake flags.
