openssl: Only use CRYPTO_set_id_callback on OpenSSL < 1.0.0

Since 1.0.0, this function is deprecated. A new function,
CRYPTO_THREADID_set_callback is available, but if not set at all,
it uses the address of errno as thread id, which should be
sufficient for most systems.

On windows, it never was necessary to use this function even
before 1.0.0, it used the right win32 API function for this
by default.
