Fix pthread_mutexattr_gettype returning different type.

We move the NORMAL->DEFAULT conversion to pthread_mutex_init(),
so get/set on the mutex attribute structure works as expected.

        * pthread_mutexattr_settype.c (pthread_mutexattr_settype_worker):
        Remove PTHREAD_MUTEX_NORMAL -> DEFAULT conversion.
        (__pthread_mutexattr_settype_old): Set NORMAL flag
        * pthread_mutex_init.c (__pthread_mutex_init): ... and move to here.
