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
