dtls: detect encrypted handshake messages

Build Information:

--
Most of my encrypted DTLS handshake packages were not detected correctly and
wireshark showed a malformed Hello Request, because the first byte was 0. The
finish handshake message is send encrypted.

This patch adds a check for the length of the handshake package like it is done
in the TLS code, this will increase the probability of detecting a encrypted
handshake package.

This was mostly copied from the TLS code.
