TinyCrypt SSL: Extend scope of TC-based SrvKeyExch writing

Browse source 
Previously, TinyCrypt was only used for ECDHE-ECDSA/RSA ciphersuites.
This commit is a step towards using it for _all_ ciphersuites involving
ECDHE (specifically: ECDHE, ECDHE-PSK, static ECDH), extending the scope
of the use of TinyCrypt in the writing of the ServerKeyExchange message.
