[issue30869] regrtest: Add .idlerc to saved_test_environment

Terry J. Reedy added the comment: #27534 is about reducing run's imports. I believe that the current patch may remove one path by which config is indirectly imported. While writing msg297983 of #30868, I remembered that config files are not the only files put in .idlerc. So a solution to
