external/boringssl: disable ChaCha20-Poly1305 cipher suites.
These cipher suites aren't IETF defined (and the IETF will define them
slightly differently when it finally does assign real code points to
them.) Since an Android system release endures for many years, this
change removes support for them so that we don't have to worry about
this temporary design for years to come.
