Remove the grace period wolfSSHd test. It asks for a password, and when running as an action it doesn't have stdin, so it fails. The test works when stdin is available.
Remove the check for __uint128_t from configure. wolfSSL exports this value, if present, in its options.h. After wolfSSL v5.6.4, wolfSSL also exports this to options.h when building it with CMake. The check in wolfSSH isn't necessary now.
