mdbx: minor workaround for HarmonyOS's bug.

Browse Source 
The libc from HarmonyOS SDK erroneously defines `EOWNERDEAD`,
`_POSIX_THREAD_PROCESS_SHARED >= 200809` and `PTHREAD_MUTEX_ROBUST` but
the same time doesn't provide `pthread_mutexattr_setrobust()` and
`pthread_mutex_consistent()`.

This commit add a minor workaround for such bug for successful building
without explicitly defining `MDBX_LOCKING=2001`.
