Adjust EVP_chacha20()'s behavior to match OpenSSL's semantics:

The new IV is 128 bit long and is actually the 64 bit counter followed
by 64 the bit initialization vector. This is needed by an upcoming
change in OpenSSH and is a breaking change for all current callers.
There are language bindings for Node.js, Rust and Erlang, but none of
our ports use them.

Note that EVP_chacha20() was first introduced in LibreSSL on May 1, 2014
while the entirely incompatible version in OpenSSL was committed on
Dec 9, 2015.

Initial diff from djm and myself, further refinements by djm.
