Make parsing of ServerKeyExchange work for D(TLS) < 1.2.

Now we only parse the SignatureAndHashalgorithm field in cases where it
is present. This change also takes care to respect SCTs, which do
include the SignatureAndHashalgorithm in their digitally-signed struct,
even when used in protocol versions that do not have the
SignatureAndHashalgorithm in the protocols digitally-signed struct.

I also added tests to make sure this does indeed work with TLS 1.1 - it
turns out that so far we did not have a single TLS 1.1 pcap.
