Updated test suite adapters for CLERIC, cl-erlang-term, and cl-epmd

The test suite adapters for CLERIC, cl-erlang-term, and cl-epmd are now using the new 'all-tests' suite in these projects so that cl-test-grid doesn't have to be updated every time a new test suite is added.

I also cleaned up a little. erlang-term-test is now recognized by Quicklisp, so we don't have to add it manually to the ASDF registry anymore.
