The test function to determine whether we have reached the end of the list was

too complex in the test case.  We can just simply test that the SBValue object
is a valid object and it does not correspond to a null pointer in order to say
that EOL has not been reached.

Modify the test case and the lldb.py docstring to have a more compact test
function.
