Really free the list with sensor modules when shutting down. No idea how I
dropped that as I found it in one old local version I had. Thanks to Mike
for the notice and valgrind for the tooling.
Also make sure we don't corrupt the list before we can free it.

Seconds is not really a suitable resolution for sensor data read outs. This
also aligns it with the tizen module and the public API.
The sleep is no longer needed in the test program either.
