systemc: Add a filter file for the tests which are expected to work.

Not all of the tests this filter accepts actually work, but we haven't
yet explicitly decided not to try to make them tests work yet.

Recording this in a file makes test runs more repeateable, and creates
a place to record why certain tests or groups of tests are being
excluded.
