Add additional system.Configs to Miscellaneous (chipsalliance#1790)

This adds untested freechips.rocketchip.system configurations to the
Miscellaneous regression suite. These, along with the previous example
RoCC config will be built by Travis. This prevents regressions at the
compilation level, but makes no guarantees on functionality.
