EAP-TLS peer: Disable TLS v1.3 by default

Browse source 
The current EAP peer implementation is not yet ready for the TLS v1.3
changes with EAP-TTLS, EAP-PEAP, and EAP-FAST, so disable TLS v1.3 for
this EAP method for now.

While the current EAP-TLS implementation is more or less complete for
TLS v1.3, there has been no interoperability testing with other
implementations, so disable for by default for now until there has been
chance to confirm that no significant interoperability issues show up
with TLS version update. phase1="tls_disable_tlsv1_3=0" configuration
parameter can be used to enable TLS v1.3 (assuming the TLS library
supports it; e.g., when using OpenSSL 1.1.1).
