gnutls: drop PACKAGECONFIG options for SSL v3 and TLS v1.3
By including PACKAGECONFIG options, the recipe takes responsibility
for defining the default state of these options. Although the recipe
currently aligns with the gnutls defaults (ie both disabled) tracking
new gnutls releases will be a maintenance effort. Unless there's a
clear reason to do otherwise, it seems safer to leave the choice of
which SSL/TLS versions to enable by default up to the gnutls
developers.
