tor on OpenSSL claims not to support LinkAuth=1

HAVE_WORKING_TOR_TLS_GET_TLSSECRETS is defined in tortls.h, which protover.c and test_protover.c do not include.

Therefore, every Tor on master now thinks it only supports LinkAuth=3:

#ifdef HAVE_WORKING_TOR_TLS_GET_TLSSECRETS
    "LinkAuth=1,3 "
#else
    "LinkAuth=3 "
#endif
