misc: Reorder sources in util/tlm and rewrite build scripts

* Use one SConstruct to build everything instead of one SConstruct for
  each example.
* Introduce SConscripts for sub-directories.
* Build in 'build' instead of the source tree.
* Build and link to SystemC from the ext/systemc directory. This
  ensures that SystemC does not need to be installed on the host and
  avoids possible issues caused by an incompatible SystemC build.
* Update the README and add some minor fixes
