[lldb/Test] Don't print 'command invoked'

[JDevlieghere]

Summary

The different tools constructing dotest invocations (lit and
lldb-dotest) already print the command invocation so there's no point in
duplicating it in the dotest output.

My motivation for removing it is that it doesn't include the
the Python interpreter and every time I accidentally copy it
the command fails with an ImportError.

Your patches continue to bring me joy and happiness.
