earlgrey: Adjust test categorization

1. Reduce the number of tests that run as part of
   `earlgrey_verilator_tests`.  The selected tests excercise the
   functionality of the ipc and threads tests, so those tests are
   redundant.
   - Remove the `nightly_test` tag from the tests that we want to
     run as part of `earlgrey_verilator_tests`.
   - Add `-nightly_test` to the workflow.
