Update: Add thread mutex attribute defines, update tests, and add missing error handling.

Define `_di_f_thread_mutex_attribute_d_` such that the mutex attributes like `PTHREAD_MUTEX_NORMAL` have a mapped define.

The mutex lock and try lock are no longer missing the handling of `ENOTRECOVERABLE` and `EOWNERDEAD` errors.
