ssl: check for minimal SSLv3/TLS record size

When a TLS record is fragmented over multiple TCP segments, with its
first byte in one segment, and the remainder over the others,
ssl_looks_like_sslv3() throws an exception because it tries to access
the third byte.

This breaks the encryption state, resulting in very weird (scrambled)
decrypted data. To fix this, check the record size before using it. Also
add TLSv1.1 and TLSv1.2 as known version.
