Route ERR_clear_error through dlsym wrapper in DLOPEN builds (#2484)

The EVP_DigestSqueeze probe added in #2433 calls ERR_clear_error()
directly instead of through the OSSL_FUNC() dlsym wrapper, and
ERR_clear_error was never added to ossl_functions.h. In a build with
OQS_DLOPEN_OPENSSL=ON, liboqs is not linked against libcrypto, so this
leaves an undefined ERR_clear_error symbol in liboqs.so. With BIND_NOW
(the default on most modern Linux distros) the symbol is resolved at
dlopen() time, so loading the library fails:

  OSError: liboqs.so.9: undefined symbol: ERR_clear_error

Add ERR_clear_error to the dlsym function table and call it via
OSSL_FUNC() like every other OpenSSL function.

Fixes open-quantum-safe/liboqs-python#122
