Fix potential stack buffer overflow in ecjpake
...
Two causes:
- the buffer is too short (missing 4 bytes for encoding id_len)
- the test was wrong
Would only happen when MBEDTLS_ECP_MAX_BITS == the bitsize of the curve
actually used (does not happen in the default config).
Could not be triggered remotely.

Blind operations on the secret
...
I'm not sure this is necessary, because it is only multiplied by xm2 which is
already random and secret, but OTOH, xm2 is related to a public value, so
let's add blinding with a random value that's only use for blinding, just to
be extra sure.

- reference handshake tests that we get the right values (not much now, but
much more later when we get to deriving the PMS)
- random handshake in addition tests our generate/write functions against our
read functions, that are tested by the reference handshake, and will be
further tested in the test suite later against invalid inputs
