cinap_lenrek 57d95c7325 libsec: move zero check to curve25519_dh_finish() 
As checking for all zero has to be done in a timing-safe
way to avoid a side channel, it is best todo this here
instead of letting the caller deal with it.

This adds a return type of int to curve25519_dh_finish()
where returning 0 means we got a all zero shared key.

RFC7748 states:

The check for the all-zero value results from the fact
that the X25519 function produces that value if it
operates on an input corresponding to a point with small
order, where the order divides the cofactor of the curve.
