BoringSSL: Make SSL_set_ssl_method() conditional on EAP-FAST

This function does not seem to be available in BoringSSL. Since it is
needed for EAP-FAST (which is not currently working with BoringSSL),
address this by commenting out the EAP-FAST specific step from builds
that do not include EAP-FAST support.
