tests: move pySim-trace test and its data into a sub directory

We currently have the test data for pySim-trace in pysim-testdata.
This means we mix the test data with the data from our original
pySim integration tests. This is very confusing. Let's put the
test data and the testcase for pySim-trace into a dedicated
sub directory.
