Bug 1243

I suggest to remove the report of what modules are built/not built upon exiting waf shell; this information is relevant to ./waf build, not ./waf shell.

$ ./waf shell
Waf: Entering directory `/path/to/ns-3-dev/build'
Waf: Leaving directory `/path/to/ns-3-dev/build'
$ exit
exit
'shell' finished successfully (2.378s)
